Lab Expansion and Mission Prerequisite

This adds 6 new rooms to the underground lab complexes.  The three existing room layouts (single big room, tic-tac-toe layout, and cross shaped) will be used 3/4 of the time and the other quarter will be split between alien containment, maintenance/utilities, data labs, and a "tribute"... (RE movie, hive elevator and flooded lab).  The other two rooms, the prisoner containment and barracks/armory, generate on outcroppings where a lab room is only adjacent to one other lab.

The data lab is currently only used to convert a military black box recovered from a crash into a black box transcript.  

Note, the old lab rooms aren't meant to be rotated so there are a few hiccups that occur due to the old code but nothing too bad.

Yay, the basic code for stringing missions together was already there but wasn't easily accessible.  "Patriot" is strung together as the example.
