Refactor GL Touch Joystick (PART I Native changes)

Browse Source 
- Move touch-handling code for "regular" touch joystick into separate file
    - Add new touch-handling code for "keypad" touch joystick.  This is a somewhat complex state-machine to determine
      which key to press depending on a full keypad rosette.
    - Adds a callback to vm.c to hook into keyboard read callback.  Allows us to immediately queue the next key if the
      keypad touch joystick is long-pressed for either axis or button keys.
