read-only repository objects.

change structure of filename for bug reports in Beremiz and
PLCOpenEditor so bug reports could be easily sorted by name

fix target Xenomai missing functions

update messages.pot and messages.po

mki18n.py: generate messages.po (contains English strings in msgstr)

This po file is necessary because Transifex translation platform
automatically can only import PO files. Usually messages.pot is
enough.

add to i18n/README forgotten commands to add some XML schemes as source
for strings and update app.fil

Backout commit 92537ed because of writing localized string in node *.xml file

fixes double mouse capturing after forcing variable in debug mode
this problem appears on Linux

fix bug with TextViewer instance in debug mode, appears after transferring new program on PLC
TextViewer isn't able to display debug values, so calling for this class SubscribeAllDataConsumers method causes error

fix problem with hidden FindInPou dialog with wxPython 3.0 on Windows

FindInPou.IsShown() returned True, but dialog was hidden.
At same time On GNU/Linux with wxPython 3.0 there wasn't such problem.
So it's Windows specific.

enable non-latin variable descriptions in CodeFileEditor

fix following backtrace:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-7: ordinal not in range(128)
Traceback (most recent call last):
File "beremiz/editors/CodeFileEditor.py", line 610, in GetValue
return str(self.data[row].get(self.GetColLabelValue(col, False), ""))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-7: ordinal not in range(128)

disable empty coils and contacts in LD/SFC editors

Closes #30

remove debug code

make all dialog have non-fixed size

this fixes the problem, that some controls may be hidden in some cases, because
dialog size is too small. This can happen when system fonts are bigger
than expected, default system them controls are bigger or if localized
strings are bigger than in English.

avoid infinite loop in search

for example following regexp '()' creates infinite list of result

make adjustable size of ArrayTypeDialog

fix problem with initial values for array of structures

for structures wrong empty repetition attributes were generated

add information about community support channel to Beremiz and PLCOpenEditor

cleanup wxHMI example

cleanup wxGlade example

add comments to wiimote example

fix running wxGlade on current Debian systems

wxGlade was moved from python import path to /usr/share/wxglade

rename text field in SVG graphic to match IEC code in svgui example

This caused svgui example to crash.

disallow setting IEC location addresses for TIME, DATE, DT and TOD variables

Size of these types is not defined and depends on the implementation
(IEC 61131-3 2.3.1).

if there is no users matiec installation, then use system path to run iec2c

search for matiec libraries in system path as well

Closes #29

remove child node from add child node menu, if max count of the same type nodes reached

fix reducing groups with ordered elements

fix extra brace

add getCompiler and getLinker methods, to abstract from XSD.
add calc_source_md5 as it's more convenient especially for embedded
targets to add -DPLC_MD5="something" option at compile time than
to mess with editing binary.
add some more helper methods

make run Beremiz and PLCOpen Editor, if full path contain non-lating
characters

There was a problem in About dialog and in project properites tab and
probably in my other places, when str is automatically converted to
unicode string using ascii.
This patch converts str to unicode using proper encoding at the very beggining.

fix clearing project name on opening project properties page.

The problem exists only on Windows with wxPython-3.0.

This happens because callback for EVT_KILL_FOCUS for a first text
control (project name) is called just after creating page with project
properties. It happens before initializing text controls from PLCController.

fix problem with debugging external string variables

Debug update stopped if external string variable added to debug
variable panel.

fix problem with clearing non-empty location field after changing type of config variable

introduced by cd9db17 ("clear variable location cell in variable
panel, if variable class or type changed").

Closes #26
