Changed the XP from attacks so you still get some XP when you beat weaklings.
Added guys' scenario performance stats so the results screen isn't so wrong.
Added feedback to loading a saved game and made controller input leave the save and load screens just like mouse input does.
Added prompt to confirm starting a new game when you already have a team.
Added a better interface for overscan adjustments.  Still need an actual adjustment screen.
Added overscan adjust screen when ENABLE_OVERSCAN_ADJUST is defined.
Added saving and loading of overscan setting via save_settings() and load_settings().  The same file will probably be used to fully replace the old config file later.
