fix issue, then it wasn't possible to view FBD programs

the reason for that is possible wx-3.0-gtk2 bug that happens if
ALWAYS_SHOW_SB is set.

fix issue, then it wasn't possible to remove functional blocks from
project using right click and popup menu.

The problem is that, PopupMenu was called using IDEFrame object and as
a result item in ProjectTree loosed focus and focus went to IDEFrame.
Therefore later functions couldn't detect which item in ProjectTree
was selected.

make attribute CFLAGS and LDFLAGS optional and add default empty value

Actually CFLAGS and LDFLAGS are not required and can be empty.
Without default empty value if target platform in project settings was
set to "Linux" CFLAGS and LDFLAGS was initialized with NoneType.
The result was broken build and it wasn't to save/load project with
such settings.

Fixed win32 build warning caused by leftover debug code

Fixed win32 runtime crashing when attempting to log before errors before PLC start. Added pictures to wxHMI and fixed it so that it loads on windows as well

Fixed canfestival extension own path resolution

Changed runtime's global PLCID to PLC_ID, working around redefinition in windoze' headers.

Extended wxHMI test

Added wxHMI test

merged forgotten changesets

Added log message when RETAIN memory not valid

Fixed leftover typo

Added PLCID variable accessible from C side, set with binarie's MD5. Added retain init and cleanup calls. Extended tests/python to test PLCID

Splitted plc_Xenomai_main.c to enable further customization

add pyrossl client side

fixed build of some tests

Fixed Nevow website startup

Fixed build of tests/python.

Added Ronan Bignaux (genesis) patch to use wxversion. Fixed side effects with sys.path. Other cosmetic fixes about path included.

Fixed SFC code generation bug detected by Mario

Added __ext_name__ variable accessible from user python code, reflecting extension name. Fixed contend of OnChange field in PLCGlobalsDesc

Added more columns in variable list of extensions' code editors - updating python's PLCGlobals from PLC logic can trigger asynchronous 'OnChange' python call

Fixed systematically loading PLC binary at startup even without -a parameter. Extended py_ext extensions instances variable description (PLCGlobalsDesc). Now contains list of variables organizd by extension, with extension name

Split runtime's twisted modules import and setup to ease runtime extensions hotpatching

More versatile registering of wamp callees

Added forgotten wampconf.json in tests/wamp

WAMP : prefix callee names with given ID so that multiple PLC and IDE can join the same realm

Fixed race condition preventing to stop PLC through WAMP

Added auto-reconnect for runtime. Fixed Beremiz closing problem caused by remaining twisted reactor thread in IDE.

Runtime : Added PLCobject methods registring. IDE : Added WAMP connector. Still need some fixes

Added stub code for runtime WAMP client. Added runtime command line switch to select WAMP url and Nevow web site port. Web port is now fixed, next port number is not tested if bind fails.

Moved twisted/nevow/athena away from Berermiz_service.py + some minor cleanup

Added Beremiz_service.py command line switch to load python extention for runtime independently from PLC program

py_ext user python code can now know about global variables shared with PLC. updated tests/python accordingly

Fixed python runtime trace thread auto suspend. Now suspends after 3 seconds when no trace is requested

Added runtime side trace buffer, handled in a separate thread, limited to 1MB, and dropped after 3 seconds if not used by IDE. GetTraceVariables is not anymore blocking on next PLC cycle

Moved trace buffer unpacking in the IDE. Latest traced variable samples are now passed as a single string

Optimized plc_debug.c generated code. Should produce smaller code size. Added statically initialized array for PLC tracable variable description.

more minor cleanup

minor cleanup

merged forgotten changes

Simplified use of runtime's global variable __common_ticktime accross extensions.

Use '-p' command line option when running matiec (iec2c)

Add command line option '-l' when calling matiec

Change location of directory containing IEC standard library in C format.

Added highlighting of wrong SINGLE task trigger

Fixed incomplete task grid update on interface change, in Resource editor

Enable overloading of availables languages in POU creation dialog

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

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
