Zombie Fortress 0.5.7 Released

Changes from 0.5.6 to 0.5.7:
- Survivor weapon anomalies fixed.
- Redesigned zombie tracking.
- Balance is made more reliable. You should no longer be a zombie twice in a row or a survivor three times in a row. If this does not occur, it was intercepted due to the fact that the starting team ratios would be upset. You are more likely to switch to the proper side next round.
- Various glitches fixed.
