More wx.NewID abuse removal. All Viewer.py got cured.

More wx.NewID abuse removal. This one was apparently silently unbinding toolbar butons when running out of mew wx IDs.

Dyslectic typos

Close branch py3-fix.

Close branch 1.1 Korean release.

Close branch generate-button.

close #2486 head

Close branch nevow_service_rework.

Close branch wx3-fix.

Intermediate merge of wx.NewID_abuse_fix branch but kept debug code in the branch. This is still work in progress, banch is NOT closed.

Continued wx.NewID abuse removal in Viewer.py : Added AppendItem to use instead of AppendMenu, made examples with AddBlockPinMenuItems and AddAlignmentMenuItems

Continued wx.NewID abuse removal in Viewer.py : get rid of one call to AppendMenu method, having no real purpose apparently. To be continued.

Start fixing wx.NewId abuse in viewer.py. This shows how to avoid using AppendMenu() function, definitely useless.

VariablePanel's menu do not waste Wx IDs anymore (directly binds wx objects rather than crating new ID wit wx.NewId)

Instrument IDE code to find code abusing wx.NewId.

Fix error when searching accross project. Collection of result wasn't initialized and was failing in case some CTN was returning no result.

Make spaghetti-code-quality great again.

check_source.sh: fix sed error: -e expression #1, char 25: Invalid range end

Update Beremiz dependencies because of added PYROS:// support

Fix header and convert comments to docstrings in PSK_Adapter

Fix Pyro work with SSL wrapper (sslpsk)

Following error was shown in Beremiz console:
PYRO connecting to URI : PYROS://127.0.0.1:3001#beremiz
Exception while connecting to 'PYROS://127.0.0.1:3001#beremiz': non-zero flags not allowed in calls to recv() on <class 'ssl.SSLSocket'>
Connection failed to PYROS://127.0.0.1:3001#beremiz!

Reason is that Pyro calls socket recv() with MSGWAITALL flag, that causes ValueError exception.

https://docs.python.org/2/library/ssl.html
recv(), recv_into() (but passing a non-zero flags argument is not allowed)

Fix crash in runtime if PSK secret is missing
