-----------
Blender/Python API
Send the full python stack trace to the reporting api,
added BPY_exception_buffer which temporarily overrides sys.stdout and sys.stderr to get the output (uses the io module in py3 StringIO in py2 to avoid writing into a real file), pity the Py/C api has no function to do this.
fix for crash when showing menu's that have no items.
