Patch Notes for a2!

- The water level has been decreased, forcing swimming to only take place in half of the trench
- A small plank has been added between the control point and the small health-pack island, making it easier to travel between the two and adding another route to the Control Point
- A 3D skybox has been added (but it's still a WIP)
- Fog has been added
- HDR settings have been added
- The area behind red spawn has been given significant attention (Blu is next)
- Heavy's head has been shrunk slightly, to better display his larger size
- Pyro no longer generates spells from the resupply cabinet or from spawning. Also lost access to the Thermal Thruster due to the use of Jump spells.
- Sniper and Medic's ammo has no longer been modified. Instead, their reload speed has been slightly increased.
- Knockback from damage has been reduced.
- Engineer's Manntraps deal more damage and freeze players for a short period.
- Engineer's Furnace has further range to ignite enemies.
