Windows 8/8.1 performance fix + French localizaion

Dear players,

Fixed the issue when the game refused to play nice with Windows 8/8.1, was related to how Windows 8/8.q2 handles color palette emulation. Thanks to Filip Frackiewicz and the team it's fixed now.

Additionally, we have added French translation to the list of supported languages.

Cheers, BFG Team
