The Crab Lab v2.0

Instead of adding new stuff aimlessly, I decided to fix a few things mentioned about the first release and upload the .rmf so that other people could test out their ideas. I'm probably not going to add anything else to it so I figured I'd let others add to it if they wanted to. I think it would be cool to see a bunch of different versions of the map made by different people. Anyway, enjoy messing around with it! (I have deleted the previous release btw!)
