New Movement Tests

- I'm overhauling the player controller code for something more organized and streamlined. 

- I'm also taking the opportunity to add new abilities like a wall jump and wall hop to make FALL WALKER's movement more dynamic.

- The vision for the gameplay flow when it comes to fighting/action is to pit FALL WALKER against seemingly impossible odds but give him the resources and abilities to prevail. I want the player to feel a sense of mastery when they have found the major abilities and can now face off against deadly foes that gave them a lot of trouble earlier.
