Added new ability ("shockwave"), code cleanup

Ability 4: Click and Drag. Upon release, a purple box will appear and
move in the direction of the drag. The purple box emits a force similar
to Ability 2.

Cleaned up other portions of the code (moving sections of code to more
appropriate entities).
Added New Enemy

- New Enemy Prototype was created with basic AI
- Fixed delta_y, delta_x calculations throughout program to account for
potential divide-by-zero errors
- Added Enemy to Level
Created new level to test resolution
Added FPS debug tracker and jittery camera movement fix

overlap. Also fixed player jitter when moving which improved overall
FPS.
