Implemented first Iteration of Boss AI

- Implemented all needed animations for Bowser (jump, walk right, walk
left, spray fire)
- Implemented AI to detect where Mario is from Bowser, and Bowser will
react accordingly (if farther then 30 Pixels, he will approach), if less
then 30, he will attack
- Implemented AI to detect when Mario jumps, Bowser will react, and jump
himself using a QuadraticBezier calculation
