Committed Cael Aislinn's proposed commit: http://forums.nanotrasen.com/viewtopic.php?f=16&t=11641

- Xenos suit and helm (completely obscuring, and almost indistinguishable from drones) (admin spawned only for now). 
- Facehuggers now have different icon states for being thrown and after impregnation. 
- New death, unconscious and sleeping icons for aliens. 
- New icon (and projectile type) for neuroxotin. 
- New infection overlay images for telling aliens about pregnant humans (3 icons, showing the progression of the infestation). 
- New system for handling alien impregnation (alien embryos are an object inside the mob, instead of a disease). 
- Players can be operated surgically to remove the alien embryos (targetting the chest: scalpel, surgical saw, hemostat, retractors. If the embryo is nearly fully developed, it might come out alive though. 
- Corgis can now get impregnated. 
- There is a short animated overlay of a chestburster when it comes time to burst chests. 
- Alien larva now have three different icon sets, depending on their growth (25% they are bloody and pale, 25% - 75% they are pale, 75% onwards they are deep red).


Fixed up table smashing, and added rack smashing in the same way.
Added new north/south facing for the large alien queen.
Updated the changelog.
