.cpp file only.

Added French localization by badmoon22. There's no need to update from 3.0 unless you play a French version of the game and want the mcm translated.

If upgrading use any script cleaning tool of your choice and completely remove any previous version (scripts are prefixed with PWER_).

Added Russian localization by Moorichka. Also corrected a mistake I made with the French localization file. Again no need to update unless you play a Russian or French version of the game and want the mcm translated.
