Swap CTN code gen and Libraries code gen, because SVGHMI use both, and need the library part to produce hmitree before CTN part.

yslt_noindent : Avoid YSLT's indent logic to interfere when using linequote.

SVGHMI: make a reasonably basic test

SVGHMI: filter out temporary variables created while generating ST code out of FBD.

SVGHMI: added deduction of HMI tree from list of HMI_* instances.

SVGHMI: added extraction of SVG bounding boxes, obtained from "inkscape -S", and passed to XSLT transform as variable.

Allow using docutil.get_inkscape_path() on Linux also.

SVGHMI: little fixes to make the build go through

SVGHMI: Added XSLT transformation, Makefile to get XSLT from ysl2 (copy of plcopen/Makefile) and a minimal stylesheet to start with.

Moved XSLT model query python code so that XSLT part can be reused for other transformations (i.e. in SVGHMI)

Complete SVGUI test minimal skeleton so that it builds.

intermediate commit, work in progress

Use a POU Library's Generate_C to collect all variables in SVGHMI.

merged

Enable svghmi plugin in features, and small fixes to skeleton.

Merged default in svghmi

Skeleton for svghmi extension

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

WIP: initial setup.

IDE: Fixed variable traces graphs RingBuffers. Removed an apparently useless wxCallAfter in trend graph that was leading to pydeadobject exception on wxGTK when double-clicking.

IDE: Cleaned up some useless tests in variable trace data handling code, changed from bare numpy arrays to RingBuffers inorder to avoid RAM outage and crash after long tracing session.

IDE: Log: Prevent crash when display progress on empty log.

Copy description when DnD variables from CodeFile CTN to POUs

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

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.

Add ThirPartyPath call in util.path module, so that individual extensions don't have to each implement same logic to find dependencies

IDE: Add a shortcut to project "Clean" action : F9

Fixed misuse of GridCellEditor in DurationCellEditor, potentially leading to crash on windows.

Allow using spin() from ProcessLogger even with no logger given.

Runtime: Added PostStart methot to PLCObject, called after PLC is started, with all libraries and python object already created, and python extensions "Start" methods being called.
This is called before python thread processing py_eval blocks starts. Example purpose: attach additional ressource to web services
