A large amount of groundwork for /tg/ code. Comes with some gameplay changes.

* + You now take severe brute damage in environments over 750kPA. A new HUD icon warns you when it's above 500kPA. Space suits block this.
* > Welding fuel tanks explode when shot.
* > Riot shields prevent you from being pushed.
* > People cannot be shoved when being pulled and handcuffed.
* > The internals button on the hud now works for tanks in almost any area, such as your pocket.
* > No more popups when you insert your ID into your PDA. There's a link in the PDA menu to update info.
* - Removed photo system from ID's as it doesn't work.
