Controller Support and Fixes

Version 0.3

It's not mentioned very prominently, but this game had rudimentary controller support from the very beginning. It wasn't a priority and so it didn't get much testing. Turns out on normal controllers, the fire button doesn't work. At all. That's come to my attention now, so a round of fixes it is then!

• Fixes to controller support:
  • Fire button now works (A)
  • Can now exit pause without resetting your game
  • Can reset the game from pause with the correct button (Select)

Controllers should now be able to use L-Analog for movement, A to fire, Start to pause and unpause (or to reset when dead), Select to reset the game at any time.
