Fixed aliens spitting corrosive acid on objects that make no sense (singularities, shield walls, etc). Their corrosive acid should be reworked in the future, along with aliens in general.

Fixed the Syndie hull door computer so they cannot use it if the shuttle is not near SS13. Should still be operable by PDA regardless. Probably a good idea to change that computer entirely in the future.
Ripley files left unchecked since they don't compile.
Fixed an improper overlay pipe on the map, near Xenobiology.
Some WIP icon updates.
