Update Beremiz translations and list of translators

Added Turkish, Romania, Portuguese, Polish, Dutch, Hungarian.
Most existed translation are updated.

Use the list of supported by app translations instead of supported translations by wx

This will make possible to translate application into locales, that
are not explicitly supported by wx: for example, 'pl' or 'bn_BD', 'bn_IN'.

Suppress message box in case current locale is unsupported or missing in wx

Beremiz can still be translated into it using own locales
available in './locale'.

Add commands to pull translation from transifex

tx - transifex cli client should be installed in the system.
It's free software and is available in Debian archive.

Run following commands:
1. Init your authorization token
$ make transifex_init

2. Pull translations
$ make transifex_pull

Add custom dialog to add/edit comment block in graphical editors

That allows to edit comment and immediately see how it'll be shown on wiresheet.

Cleanup examples so they look clean, nice and almost the same on Windows and GNU/Linux

use the same font size on Windows and GNU/Linux

use nice and pretty mono font in graphical languages (SFC, FBD, LD) as well

it looks like that was original idea, but some bug squashed in and
default font was used for POU.

at the same time fix use of mono font in the header of Variable panel
for SFC/FBD/LD POUs.

Don't need to call extra _init_

_init_ is already called for value in infos["elmt_type"]["initial"]().
Additional _init_() creates second set of child element and that
creates unusable xml project.
This regression cause by not well tested commit "Proper fix for error
'object has no attribute 'getSlave' in EtherCAT extension" (96ca6b056c55595f71bfaca9f54b9e8646460c23)

IDManager: added import/export plus little cosmetic enhancements.

IDManager : refactored a bit, moved some code into PSKManagement.py. Now captures URI and PSK on new PYRO(S) and propose them when editing URI. Import/export still to be implemented.

Renaming servicetype into scheme.

Added toolbar button to launch ID Manager dialog.

Renamed IDManager control into IDBrowser, because dialog will be named IDManager

IDManager.py : finished selector mode.

Added early implementation of IDManager.py. For now only used to select ID in URIEditor

Path may contain spaces... sequel of d1359cb

'Merged' URI editor dialog and Discovery dialog, also clean up related code

Cut more useless code from URI Editor

URI Editor Dialog : moved it to /dialog, and fixed naming.

URI editor : Rewrote most of it, cleaner.

PSK : Stunnel and/or OpenSSL (undocumented) handles PSK better without special chars, apparently

Prevent PLCObject to be imported from IDE as a side effect of importing runtime package

WAMP : ensure that unicode string is passed for published events IDs

PYRO PSK: adjusted cipher and key length to be usable with openSSL 1.0.2k.

Automatically get PSK and ID when connecting to PYRO[S], so that future connection through PYROS can use that same key. Also fixed case to UPPER for *PSK.

Runtime : Ensure that a random PSK secret compatible with stunnel is generated if -s commandline switch is used. Stunnel service is restarted after generation, using spawn_subprocess. TODO : give stunnel restart command as a commandline parameter.

Added runtime/spawn_subprocess.py. Force use posix spawn instead of fork, with API similar to subprocess. Using fork in runtime is incompatible with Xenomai, because memory is locked and this can lead to out of memory error.

Small cosmetic change to enhance readability and avoid confusion.

Force Zeroconf to listen and answer only on interface specified with '-i' command line argument.

Useless __name__ == '__main__' tests.

Fixed PYRO's PSK_Adapter : monkey patching was breaking non-PSK protocol, and import ssl was missing.

merge

Fix PYROPSK protocol configuration. After a few iteration of trial and error it appears that TSLv1 and PSK ciphers needs to be specified

merge

PYRO/TLSPSK : must use PYROLOC* protocol scheme in pyro URI, otherwise object ID is missing. Had to use more persuasive pyro3 monkey patching to have PYROLOCPSK resolved properly

PYRO/TLSPSK : fixed typos, used appropriate ciphers (https://github.com/drbild/sslpsk/issues/3), use PYROPSK instead of unresolvable PYROLOCPSK.

Replaced PYROSSL with PYROPSK.
Secrets are files named $ID.secret in project's /psk directory.
Connect with URI formated PYROPSK://host[:port]#ID

Beremiz_service now binds both pyro and nevow ports to interface given with '-i' argument.

Fixed typo in Wampclient.py

Please pylint and pep8

Merged

Show more exceptions on stdout, particularly those that are raised by AutoLoad (first item in Main Thread worker)

Some cleanup in WampClient and added functions that are usefull for extensions that need to use pub/sub.

Fix non-usable toolbar on wxPython with GTK3+ in PLCOpenEditor

this problem is related to 'Fix non-usable toolbar on wxPython with
GTK3+' (5927710b). This problem does not happen in Beremiz because
additional necessary self.AUIManager.Update() is called
BeremizIDE. Therefore minimal change in the mentioned commit was
enough for Beremiz, but is not enough for PLCOpenEditor.

Avoid usage of localized strings before initialization during import in many modules

This happens if import is done before i18n setup
(InstallLocalRessources()).
This affects PLCOpenEditor mostly. Beremiz IDE is free from this issue, but moving
initialization from import should make modules more robust.
Otherwise execution result depends on where and when import was done
and this is not a good thing.

Some modules (ConfigTreeNode, features, CodeFileEditor related
classes) still have this, but they are used only in Beremiz.
Most problems result in non-working internatialization.
In some cases (VariablePanel) there is backtrace, because localized
key is not found in non-localized dictionary.

Remove executable bit from source files where it's not needed.

Avoid dictionary initialization during import in PouDialog

Because initialization happened before i18n setup, then it causes later
problems during creating new POU on non-English locales (Russian for example).

Revert commit "Dirty fix for error '_object_has_no_attribute_'getSlave' in EtherCAT extension"
[a3ac46366b86a0b237dac93be6b2281ac70b98a8].

The problem was that XML elements (proxy object) in some cases were created using custom XML
classes constructors and lxml.etree.Element() call and live python
patching. This causes that lxml backend doesn't know that custom python class
should be used for these XML elements.
Proxy object can be move/deleted and recreated by lxml
backend at any point in time or this can be done in python by copy/deepcopy operations.
If this happens, then newly created
proxy elements are using default class lxml.etree._Element. And all
custom functionality is lost.

All created XML elements should be always created through corresponding
parser and class lookup callback done by lxml backend.
It's described in more details in lxml documentation:
https://lxml.de/element_classes.html

Make comment blocks in examples slightly bigger so text inside is always visible

Update requirements to include WAMP support

Use static library for Modbus

It makes easier deployment of projects with Modbus (similar to BACnet implementation)

Cleanup WAMP example

Closes #39

Update README for WAMP example to use crossbar with python3

crossbar python2 support is broken in v18.7.2.
I've submitted with fixes for that.
https://github.com/crossbario/crossbar/pull/1376

But they don't test crossbar with python2 in CI, so it's going to be
broken again in the future.
And there is no much reason to use crossbar with python2.

Make ID in WAMP project match with ID PLC runtime.

See project_files/wampconf.json. ID for runtime is "wamptest". The
same id should be used in project's location URI: WAMP://127.0.0.1:8888#Automation#wamptest

Fix wxHMI example after upgrading wxGlade

Newer wxGlade generates code to initialize GridSizer's with empty
elements.

...
grid_sizer_1.Add(self.window_1, 1, wx.ALIGN_CENTER, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
sizer_2.Add((0, 0), 0, 0, 0)
...

That causes following traceback, if new buttons are added
to already full sizer.
