Zombie Fortress 0.5.0 Released

0.5.0 is the beginning of Zombie Fortress beta. Yes, up till now I considered it to be the alpha.

Changes from 0.4.7 to 0.5.0:
- Spies can now permanently cloak.
- Medic uber now again lasts 10 seconds.
- Medic overheal now increases health only to 125%.
- Engineer Sentries should no longer lose health too quickly or not at all.
- Auto-balance should be finally fixed.
- Axetingusher will no longer be useable.
- Survivors can no longer have the zombie weapon configuration applied to them.
- When the last survivor leaves, the zombies win.
- Ben is no longer killed.
- Turkey is fixed.
- Lots of optimization.

Current Code Length for 0.5.0: 970 (+3 from 0.4.7)
