-Breathing plasma will now give you the plasma reagent for toxic damage which will need treatment, in order to remove it from your body quickly. This creates a nice poison effect.

-Made the plasma reagent damage you more.
-Syndicate agent cards will now work inside pdas/wallets.
-Switched some comments around in event.dm
-There was a bug with a local variable list which became null, the problem was that there is no where in the code which could've nulled it. My only theory is that not having . = list() first maybe caused problems, but it seems unlikely. I changed it anyway and I'll keep watch for it re-appearing.
-Fixed a bug with the new firedoors not keeping out heat, since they have an opacity of 0. I switched everything around to accommodate this.
