Demo ready

I may have one more build ready by Tuesday.

The biggest change is adding a pop up window that warns you if you haven't finished moving Torrin when you try to move Sir Camil (and vice versa.)

I noticed there's a memory leak that takes about 15 minutes to crash the game on average. I have an idea of how to limit its impact but I'm not sure if it will be ready by Tuesday. Wish me luck!
