+Pythonize FIFE

+Import this extension to get a more
+pythonic interface to FIFE.

+Currently it implements the following
+conveniences:

+* FIFE Exceptions print their message.
+* Automatic property generation for:
+  * fife.Engine
+  * fife.Instance
+  * fife.Image
+  * fife.Animation
+  * fife.Point
+  * fife.Rect
