Pre-Alpha v0.2.0: Cool Visuals, Even Better Movement

Hi. Overhauled the visuals and added some cool improvements to player movement. Added some extra common sense to the mix.

- You can no longer pick up an item that you aren't looking at

- Press [c] to crouch

- You can no longer sprint backward

- Camera no longer bobs while you're in the air

- You can actually see the item you're moving now because it will follow the cursor
