Made a lot of modifications to accommodate rotation. Still bullet and collision detection to fix. Also getting a ton of jitter from the Wiimote.
Bullets now fire and move in relation to angle of player.
Added back collision detection (looks awful but alright for proof of concept). Made a change to the way the rotation code works - now the server is the only one that updates the sprite's position after rotation.
Merge pull request #21 from jamesmack/testing/rotation
