Binary update v0.9.1

We've finished porting the game to the latest graphics engine version (Ogre3D) and to the latest compiler. This version should run about 37% faster in frame rate than the previous version. I know we don't need optimizations since this game is quite fast and smooth even on old graphics video cards but we needed to modernize our development tools.
