Office population essentially done. One thing that came up is that I need to tweak nodes further to guide the guard out of a room. Doing that now.
"Guide Rail"/Exit nodes implemented, office random population implemented. Office still needs powerup to spawn in it.
Few more tweaks. Squished some bugs, turned a crash into a non-crashing Array Range Exception.
Merge branch 'master' into zhandev
