[pygame] RPG Engine

I've put up a draft of a new game engine, based on my previous program 
"Morningside". It can serve as the basis for an RPG engine. It offers 
tile-based movement and items, with the logic needed to create items and 
characters, pick things up, move around, and load levels from text 
files. You get a "Zone" class that holds a potentially large area 
(100x100 tiles for an example). For a larger game you could add a means 
of switching to a new zone, or loading more than one at a time. It's set 
up as a 2.5D system in the sense that there's a 2D plane with a 
heightmap. It's meant to be separate from any graphics system (just a 
"model" in the MVC concept), but there's a demo class that turns the 
data into an image, and you could easily extend that (or even adapt the 
Morningside code) to show actual graphical tiles.

This project came about because I'd been wanting to improve on the 
little sim-world I was using for AI stuff, and I tried a Roguelike 
called "Elona" that was too frustrating for me, but with some nice 
graphics and some interesting gameplay.
