Collision Optimization

[underGhost]

Currently there's two packages checking for collisions SAT and Quadtree. We only need to utilize one.

• Switch over to Quadtree to handle all collisions.
  • Handle collisions by type. (ie Player, Virus, Food, Bot).
  • Quadtree needs to be a manageable package instead of quadtree.js

Currently used quadtree.js is not on NPM, may have to adapt to another package of similar functionality

I may look into https://www.npmjs.com/package/simple-quadtree

I've replaced the currently used quadtree.js with simple-quadtree in #409 (at least for the es6-refactor branch), but in that PR we're still using SAT because I've not had time to do that...
