+Door Region: STRING
-For mainhall.tbl
-sets the region for the door (options, exit, ready room, etc.)
-Optional
-Could make duplicate doors.. that's up to the tabler to fix!
-allow Lab and Multi to be settings among others
-Goober's Thoughts
---<@Goober5000> the best way to specify a door action would be to indicate an event in the state machine
---<@Goober5000> the game has a state machine
---<@Goober5000> i.e. it has a number of defined states, meaning configurations or modes
---<@Goober5000> gameplay vs. viewing main hall vs. viewing options, etc.
---<@Goober5000> so if you say "clicking on this region will trigger this state" you could make your region to any number of useful things
