Camera System

[WillNilges]

Bug list from #5, continued. Most of my troubles are being caused by the damn camera.

• [x] No way to tell which way the characters are facing
• [x] Attacks are sent in a direction based on which way the character is moving, not which way they are facing
• [ ] Characters get stuck on the floor for a frame
• [ ] Can infinitely "climb" buildings
• [x] No character sprites
• [x] Can jump in the air if they haven't left the ground
• [x] Air control is inconsistent and feels like shit
• [x] Acceleration and turning may benefit from being snappier
• [x] Unidirectional Knockback
• [ ] Comments make no sense
• [x] Camera has weird-ass offset
• [ ] AETags on players are reversed?
• [x] Player scaling is all fucked.
