Refactor 6

[michaeltintiuc]

This is the sixths step of refactoring:

• Cleanup Player component
• Improve collision
• Improve movement

We've further cleaned up the Player component by removing DOM access function and simplified the collision logic by creating Rect and Collider helper classes. Each collidable component now uses a new useColliders custom hook that pushes it's collision info such as position, size, type and what happens on collision to the global context's colliders array that is then being looped within the Player component and react to collisions differently based on their type. This setup is much easier to follow, manage and update, we can easily make our coins do damage or fire yeild bonus points.
