Allows you to attach air tanks to operating tables for eaiser application of Anesthesia (or pain) (Also converts Op Computer to TSX)

[MrMelbert]

• Anesthesia (or other) air tanks can be attached to operating tables with a left click.
  • They can then be removed by right clicking with an empty hand.
• The operating computer now has a new option to enable the attached tank as the mob's breathing supply.
  • This still requires the mob be wearing an internals-compliant mask, such as a surgical mask.
  • It also won't work on mobs currently using internals, or dead.
• Included is an option to automatically disable the tank after a set period of time.
  • On by default, this is simply to ensure people don't leave people on anesthetic for forever without realizing it.
  • The default value is 6 minutes, more than enough to get most surgery done.
  • It can be disabled. Emagging the operating computer also silently disables it.

Other small stuff:

• Added brain display to operating computer.
  • Thought about adding pain as well but I'm unsure of how I want to display it.
• You can put any air tank on.
  • Yes, you can suffocate people if you use an empty tank.
  • And yes, you can hook people up to a tank of pure plasma.
  • Or if you're not insane, you can use an alternative anesthetic such as Healium, or a booster like Pluoxium.
