Beta 4:

• keyboard input configuration didn´t load correctly (was overwritten by default mappings or mappings were completely erased)
  
• if at least one rawinput keyboard and mouse is found: skip directinput keyboard and mouse enumeration. Prevents stupid side-effects if both are used simultaneously, for example fullscreen and directinput keyboard enabled: rawinput stops getting any input (and technically directinput is less direct than rawinput, it is only good for joysticks/pads today)
  
• fixed possible division by zero in new power led code
  
• statefile_quit= configuration file parameter added, automatically saves state to when emulator is quit normally
  
• CPU speed and advanced chipset configuration stored in statefiles
  
• in some situations full-window mode tried to use vsync frame wait (which did nothing and caused warp-mode like speedup)
  
• added toggle fullwindowfullscreen and fullwindowwindow input events
  
• yet another sprite update, Total Perspective Vortex / Frantic background smallest sprites missed last line of data

WARNING: Configuration files saved with previous 2.2 betas won´t be fully compatible with later versions. Keyboard input data is handled slightly differently (no more "super" keyboard that gets all keyboard input), beta 1-3 written config files may not have all keyboards enabled if Configuration #1-#3 mode is enabled. Older configuration files should work correctly.
