Okay, there's a couple things up with this revision:

Metroids:
     
     No, they're not working yet, and I planned on committing this when they were finished, but the basic framework is there. The Metroid in xenobiology now moves around, I guess, kinda like a monkey. ADMINS: !! DO NOT TRY TO POSSESS/CONTROL A METROID, unless you're willing to take a risk! I haven't tested it thoroughly yet, it might have some glitchy results!


Turrets:
     Fixed some lingering bugs with the targetting system. Hopefully these should be pretty stable now.


Reagents/Chemicals:
     I fixed some problems with virus combinations and weird stuff with the PANDEMIC machine.



There's probably some other stuff people requested I fix on IRC that I didn't mention, I can't remember anything else though. Hopefully this should stabilize some of the more annoying bugs with reagents!
