/* The following config versions are currently used:
   0: the 0.2 release config file, without config-version number
      (so that defaults to 0)
   1: Removed singleWindowMenu, newKeyboardStyle, oldStatusDisplay,
      added config-version number
      Version 1 can read version 0 without any problems, so 
      SUPPORTED_CONFIG_VERSION is 0.
   2: Changed to SDL keyboard bindings
   3: Added username (userid was used for ALL players)
   4: Added username per player
   5: Enabled jumping, which might cause a problem with old
      config files (which have an unused entry for jump defined
      --> if a kart control for (say) player 2 uses the same key as
      jump for player 1, this problem is not noticed in 0.3, but will
      cause an undefined game action now
   6: Added stick configurations.
