Bugfix:
* Fixed missing texture on 'Types of Mass Spectrometry' poster.
* Fixed scientists standing up and getting lodged in desks when returning to Map B after having left it.
* Fixed being able to screw up the test chamber double doors by messing around in the trigger area when the scientists are talking. I think.
* Made the button to open the Test Chamber doors from the inside more visible since people weren't always aware of it.

Fixed HEV suit stand missing model.

Inagugral update.
