Add "Generate Program" to toolbar in PLCOpenEditor standalone mode.

Currently you can find the "Generate Program" action only in the file menu,
but this action is very often used in standalone mode, so I added toolbuffon.

Merged search in CTN branch

Finished adding search in python and C files. Stripped debug code and useless comments. Close branch

WIP adding searching capabilities in python files. was done :
- added search in body of Code File Tree Nodes (moved editor code so that we CTN search can have the same sections text layout as editor to search in)

WIP adding searching capabilities in python files. was done :
- added search in global variables used by Code File Tree Nodes

WIP adding searching capabilities in python files. was done :
- fixed highlighting search result in text body of CTN code editor.

WIP adding searching capabilities in python files. was done :
- change stub search results to trigger highlighting un variable panel
- trying to highlight in CTN code file editors -> problem with EditorPanel not having self.VariableEditor set...
- added highlight capability to CTN's CodeFileEditor's VariablePanel

WIP adding searching capabilities in python files. was done :
- fixed stub CTN search results so that they can be accepted by search result panel
- worked on search result panel so that it can display those CTN results
- made search result panel display correctly stub search result, for variables and body matches
- EditProjectElement now opens CTN node as well as PlcOpen project nodes

WIP adding searching capabilities in python files:
- Added recursive Search capability to config tree nodes
- Added stub search to code editors, for test

Fixed more pylint reports :
connectors/__init__.py:31: [W1652(deprecated-types-field), ] Accessing a deprecated fields on the types module
in fact, it should have been unused import.

Add SpinButtons for integer and floating point variables in ForceVariableDialog

it allows to change variable value using only mouse.

Fix non-marking as manually forced floating point variable if the value isn't integer

For example, if user in debug variable panel set any floating point
variable to 34.3, then it's not shown as forced (blue color) and user
can't release this enforcement.

If user changes the value to 34.0, then enforcement shows
correctly. This is done because binary representation of floating point
numbers in IDE and runtime can be slightly different (double vs float)
and as a result values aren't equal.

Don't close ForceVariableDialog if user entered wrong new value

return back to edit field in this case

Additional fix for rewrite ForceVariableDialog commit (9076249f)

fix following backtrace:

Fix redraw problems in preview frames and debug panel

The problem was that direct call of RefreshView (now DrawView) doesn't
generate EVT_PAINT (at least on GNU/Linux with Wayland and wxgtk build
with gtk3+ support).
Now RefreshView simply triggers EVT_PAINT and EVT_PAINT handler does actual work.

Rewrite ForceVariableDialog. It's not based on wx.TextEntryDialog

Don't customize standard wx.TextEntryDialog on the fly, implement your
own dialog for that with expected behavior and without any hacks.

fix problems with recursive beremiz.h inclusion

remove LogMessage prototype from plc_main_head.c

it's not needed, because prototype is included in beremiz.h
But it caused problems with TARGET_LOGGING_DISABLE.
