Like, whoa, an update!

Changes: The background fence thing now tiles right, two new types of goop, four more signs, some unsmashed lockers, a couple more animations for our friend the computer, and integrated the background and destruct blocks previously provided.

So... I think we could probably use a bit more eyecandy, such as ruined security cameras, some office chairs, and some sort of layer7 eyecandy (mountains, plains, ruined city... something)

After that a pallet and a masking and then a release!
