Enable overloading of availables languages in POU creation dialog

Enable overloading of task triggerring source cell editor (SINGLE) in resource editor. PLCGenerator now generates MULTI keywork instead of SINGLE when task's activation is surroundes with square brackets

Updated tests/python : added derivated return type function declaration+call and re-enabled refrences to global FB interfaces

Fixed declaration and ST code gen for IEC function that return derivated types

Added a variable name text entry dialog to allow name change on drag'n'drops

'NamedConstant' variable D'n'D is now allowed on variable grid

Allow specification of command line arguments encoding in ProcessLogger

Splitted type selection menu code in VariablePanel, making easier to override behaviour by inheritence

Fixed crash at project load when features.libraries is empty (i.e. no libraries are provided).

Added plcopen.definitions.DefaultType, set to INT.

Fixed POU paste exception

Propagated changes made in matiec/lib/accessor.h _SET_VAR macro (Mario's matiec changes merged at 39086e324665) to py_ext library, and other (not compiled in) XML standard FB definitions.

Added 'NamedConstant' drag'n'drop in text programs as well (was only accepted on graphical languages).

Fixed launch of PLCopenEditor, broken since 611fded24ce4.

Organized controller's _Build sub-methods layout. Many (unwanted) white space changes.

Added 'NamedConstant' drag'n'drop in programs. It does create a simple variable with initial value and is usefull for drag'n'drop constants from extensions while keeping a name associated with constant

xmlclass : Ensured precedence of newly defined class in case of conflicting declaration

Fixed Exception dialog crash when original exception contains unicode

Fixed unused variable in plc_debug.c

On windows, prepend CWD to PATH before invoking Generic target make command

Pair with matiec a51a3bb4d613. Re-enable resource add/remove, updated CFLAGS, disabled broken global FG test in tests/python

Fixed typo in plcopen.py

Changed python_gear ratio type from USINT to UINT, less restrictive regarding range

Fixed support for spaces in matiec libraries path with native beremiz build

Delayed CANopen initialization for better busoff recovery

Fixed non initialized timer causing exception in some rare cases (continued)

Fixed non initialized timer causing exception in some rare cases

Fix matplotlib exception when launching on XP

Fixed import error when loading extensions

More gcc warning avoided

Added <string.h> to plc_main_head.c to avoid warnings.

Tidy PLCopen definitions

Removed depricated matiec stdlib-code-generator-generator

Factorized bitmap and i18n resources loading in between PLCopenEditor and Beremiz. Now in utils/misc.py

Re-introduced toolchain_makefile.py. This time, it comes with a 'Generic' target, and a 'genericmake' example

Removed dead code

Fixed xmlclass bug when enabling/disabling libraries in root CTN

RC5

Added example of SFC simulating traffic lights

Fixed bugs in SFC when loading transition condition and referenced transition or action body

Fixed bug with edge and storage parameters in contact and coil not loaded in file saved with older version

Fixed bug when defining variable type as explicit array in VariablePanel

Fixed bug with function POU when extracting return type

Fixed bug with non-ascii characters in program comments

Fixed bug when debugging wire connected to output connector with modifiers even if connector/continuation is used to replace long wires

Fixed bug in debugger when debug tick received is None

Fixed bug with decimal value string formatting

Fixed bug with decimal value string formatting

Fixed bug when graphic element position and size and connection points are decimal

Fixed bug in test if block type is used by current edited pou

Fixed bug when adding and removing function block in graphic viewer. In some cases, the associated variable could stay in the variable panel.

Fixed coil and contact dialog to let user select a complex type variable for contact and coil expression

Fixed bug Drag'n drop variables from left panel to debug panel disabled

Fixed bugs with pou variable infos computation stylesheet

Fixed bug when pasting element with an odd width or height

Fixed refresh speed so that interface is not blocked when debugging

Added support for optimizing debug, preventing to filling buffers with only the last value for debug data consumers that only show the current state

Remove old debug panels and viewers not using matplotlib

Added new debug process separating non-wx thread extracting debug values from connector and 10 Hz wx timer refreshing Beremiz debug Viewers and communicating throw double-buffering, to avoid segmentation faults and optimize CPU usage

Cleaner matplotlib import preventing noisy warnings
