- unified saved games path handling for all platforms

The current game subdirectory is now created on all platforms
Added support for -savedir command line switch for all platforms
Removed save_dir CVAR in favor of cl_savedir which was available on Windows only
Made cl_savedir CVAR global instead of different value per each game
