fix strange behavior on Backspace press in ST

Before:
if text was selected and cursor was at indention, one indention (two
spaces) was removed.

if cursor was at start position of the line, then nothing happened.

if cursor was in the middle of indention then on backspace more
indention were added


Now:
if text is selected, it will be removed.
if cursor is at start position, then new line will be removed.
if cursor was in the middle of indention one indention is removed.

fix close button in system menu for AboutDialog on Windows


If SetEscapeId receives wx.ID_CLOSE as parameter, then on Windows with
wxPython 2.8 system close button in title bar stops working.
If wx.ID_CANCEL or wx.ID_OK is used in SetEscapeId call, then close
button works correctly.

make renames caseinsensitive

update PLC status after initialization

This is necessary especially if existed PLC program is loaded, but PLC
is not started automatically. In this case taskbar icon shows that PLC
isn't empty.

always load existing PLC program from the working directory

stop PLC before unloading


This fixes segmentation fault if service was quit without stopping it.
It has happened if Beremiz service was quit using taskbar icon or by
closing Beremiz IDE (in case of autostarted local service).

In second case to trigger the bug following step has to be done:
1. Open Beremiz IDE
2. Open project, compile and connect to LOCAL:// runtime
3. Transfer and start the PLC program
4. Open other project without disconneting the PLC runtime
5. Close Beremiz IDE

add internatialization support for Beremiz_service.py

fix issue with changing annonced Pyro service name via taskbar icon

don't crash on trying to change IP interface for Beremiz_service using taskbar icon if IP wasn't previously

start/stop from taskbar icon only if PLC is stopped/started

close Pyro socket after daemon stop


without that socket port is open after daemon shutdown.
As a result if you restart daemon with new settings (service name, for example),
it can't listen on already used port and opens the next free TCP port
regardless of requested settings.

add python-wxgtk3.0 support to Beremiz_service.py

make about dialog on Windows not so big


It was automatically expanded to place description in one line.
