Workaround RubberBand drawing problem on GTK3

Depricated PyGridCellEditor becomes GridCellEditor

Fix exception when canvas becomes null because of window resize, and avoid useless parameter+condition in GetLogicalDC

Merge SVGHMI in default

SVGHMI: Widget lib: small doc fix.

SVGHMI: DnD UI: Use widget's short description, initially forgoten.

SVGHMI: Fixing last commit's multiclient implementation, in case of watchdog. To be continued, since multiclient still fail...

SVGHMI: Implemented multiserver+multiclient, but only tested with single client and single server for now. To be continued...

SVGHMI: More configuration parameters : network interface, TCP port, URL path and watchdog enabling.

SVGHMI: Added a way to distinguish watchdog-enabled HMI from multi-client HMI in URL.

SVGHMI: Prepare accepting multiple clients on multiple HMI: Use POULibrary new capability to add variables to PLC Configuration. Now heartbeat and HMI tree root are added by the library part of SVGHMI, and not by each instance.

IDE: Allow POU Libraries to inject PLC Configurations globals during build.

SVGHMI: DnD UI: Add hint instructing user to Drag HMI tree items to text field.

SVGHMI: update generated XSLT files

SVGHMI: UI Updates validity indicator when DnD HMI tree node in text field, according to node type

SVGHMI: Fixed typo in last commit

merged

Runtime: Fix exception "Worker is disabled" when connecting while PLC runtime is starting.

Pyro/wamp/UI delegate jobs to Worker, causing race condition if worker isn't already started.
Added a function to ensure that Worker is already created when pyro or UI starts

SVGHMI: UI now have multiple HMI tree variables DnD to widget paths. Still no type checking, WIP.

Finished fixing Wx IDs abuse. There was still some wasted IDs because of wx.NewId calls in many places where it wasn't needed, and those IDs were not re-used. As a consequence Beremiz was making exception crashing after a few hours of intensive use.

SVGHMI: DnD UI : changed layout again, moved description in a vertical splitter, added scrollbar for preview and signature, fixed flickering description

SVGHMI: UI: Swap widget selection tree and preview panel

SVGHMI: WIP: Widget Library UI: Reworking widget selection and binding.

Merged SVGHMI branches

SVGHMI: WIP on Widget DnD UI : Added documentation to widgets, that is injected in widget parse tree during widget analysis

SVGHMI: Fix behaviour of Jump widget, that wasn't displaying "disabled" state in some cases.

merged default in svghmi

SVGHMI: updating generated XSLT

SVGHMI: Intermediate state while updating UI, preparing for displaying widget description and multiple variables selections

SVGHMI: Extend widget labels parsing to allow expressing widget's accepted types in labels

SVGHMI: Add analyse_widget stylesheet and python code to execute it, in order to obtain widget signature independently of DnD SVG file generation.

SVGHMI: drop useless code from gen_dnd_widget.yslt2, renamed python callback to pass messages

SVGHMI: Added widget_desc to declare widget signature and description

SVGHMI: In order to allow widget signature and description to coexist in same ysl2 file, introduced widget_class, widget_defs to declare widget codegen templates and gen_index_xhtml to mark templates that are only usefull in gen_index_xhtml.xslt.

SVGHMI: keep track of order of selection in HMI tree, so that variable can be passed in same order to DnD widget

SVGHMI: fixed typo

SVGHMI: still quite naive path substitution whn prepearing widget for DnD, but now uses label generation.

Multiple widget DnD and mutiple variable still make no sense because all path are replaced with same path, but atleast min/max value are preserved...

SVGHMI: Added text box for tranformation feedback aside widget mignature
