Engine: Complete!

Okay, not complete. But full-featured. It now supports just about everything I could think of!

Unfortunately, I introduced a demon bug into the code on Sunday. Actually, two bugs which interacted to create a bizarre circumstance. It took four hours to fix, and I wasn't in any mood to keep programming after THAT.

So, no screenshot examples. I'll try to make a boss either tonight or tomorrow night. I'll give you some screenshots of that.
