Facehugger issues 2 electric boogaloo

Created by: CptWad

I opened this issue about 7 months (#4269 (closed)) ago and it was lost in time Reopening because I actually watched the very same shit happen all over again in a round

//FOLLOWING IS OLD READ FARTHER DOWN THE THREAD\

1. They do not jump on anyone with something in their mask slot. This includes (Tested) gas masks and other (dead) facehuggers.
2. Facehuggers leave a sprite of themselves on the floor when jumping on someone
3. Facehuggers do not provide oxygen(or proper air now that vox and plasman exist) anymore. (They used to, that way when dumbshit mchunter breaks a window the monkeys did not all die)
4. Facehugger AI generally wonky. In game to get people face hugged I had to drag them over an active face hugger without them having a mask or other xeno-protection gear
5. Thrown facehuggers do not land of faces. In fact throwing them is a lot like an AOE banana peel rather than a face full of xeno
