version 5

-Finally added a PvP mode!

-Created two sets of touchscreen buttons so PvP can be played on one tablet without the issue of not being able to do simultaneous button presses!

-Replaced lighting2D with my own light animation for lightning bugs since Light2D was bogging the game down.

-Cleaned up a lot of errors by replacing yield timers with actual timer nodes so when nodes are freed they don't keep trying to run functions after the yield times out.
