- added support for python plugin compilation under mingw
	- improved wordprocessor activity. it no more crashes and allow
	  two styles, on for the layout, one for the color (on an idea
	  of my daughter Clara)
	- This activity could be moved out of --experimental now but
	  we are in string freeze.
	- Added a double switch in electricity. It is now possible to make
	  a 2 switches corridor like circuit (va et vient in french).
	- config.c : fixed a double memory free on locale that crashed GC at exit time.
	- file_selector.c: fixed mime type loading and display. now uses gettext instead of
	  inline xml translation.
	- menu.c: fixed a misplaced free that makes all board description in the database to be junk
