Map tweaks, debug preset fix

Bundle of tweaks. Fixes the random ass hole someone made in virology. Also fixes up the ERT room on Centcom so a admin can keep fairly hands off, even when doing more then one role seriously why did you only put down one set of everything god damn.

Actually added the ERT preset to the debug command, as before I forgot to add it to be selected. With this, all a admin would really need to do, button-wise, is to spawn and debug someone with the preset for the basics. Then they can loot the rest from the ready room. Handy!
