TG: Tonnes of stuff, please check the changelog.

In short: massive updates to security, the library, hydroponics, the kitchen and
the bar, by Flazeo and Ikarrus
Massive updates to the PA, with Invisty's new sprites, done by Sieve
New sprites for field gens too, also by Invisty
Borg and battery updates by Sieve
Fake gloves by Sieve
I messed around with some pressure_resistance stuff on Dumpdavidson's suggestion
(only in paperwork)

PROBABLY A BUNCH OF OTHER SHIT
