Zombie Fortress 0.4.4 Released

It has been a while, but 0.4.4 is finally ready for testing.

- The way autobalance activates has been changed, alongside some other tweaks. If this rendition works, I will try to improve the timing so it activates right before the next round starts.
- Pyros can no longer use Axetinguishers.
- Heavies can no longer use the K.G.B.
- Heavies are now permitted sandvitches.
- Soldier speed increased to 280 equivalent to the demoman.
- Additional optimization.
