[DNM] Reactor QoL | Multi-Tile Poddoors

- - -
Additions:
 - Additional define for stuff super insulated against rads. This is just to remove number clogging and permit stuff to be changed on a higher level. Still needs to be added to most things, but it's a start.
 - Brings over multi-tile poddoors from TG. They're about as you'd expect.
 - Lead walls for the RBMK area. Yup.
- - -
Map:
 - RBMK reactor given lockdown shutters, a proper blastdoor and some primping up in general to the surrounding area. Additionally, they've walls now that are appropriate.
- - -
Bugfix:
 - Corrects rad shutters being wacky and out of this world.
