[pygame] Tactics Game Demo

[Kris Schnee]

Oh! I forgot to mention that I'd finished the new demo of my tactical 
combat game.

It's still messy, but closer to being an actual game in that it's got 
data loaded from files, multiple attack types, and a sequence of battles 
interspersed with story scenes.
