Fix entities in the Warp Zone's gray tileset not being gray in the editor (#480)

In-level, they were made to be gray in #323. The editor does not reflect this however; they're still shown as
green. For the same reasons in #323, this adds special cases to draw the entities as gray.
Closes #372.
Also, I changed my name in contributors.txt to be my username as I didn't feel comfortable with it being my name.
