-Increased brightness of light bulbs to 4 (up from 3). This is so I wouldn't have to spam a whole bunch of light bulbs in darker areas to get the same mood it had before the darkness update. And since I don't need them any more, I've removed a bunch of light bulbs I added in in an earlier commit.
-Added a maint door to the Janitor's closet
-Map changes to library and medbay. Thanks, Dingus!
-Updated changelog
