PyGIMP

Started working on the python bindings for gimp 1.3. It has been a long time since I had done much with that code (a lot of the code hadn't been changed in 3 years), and it was a bit embarassing to see how bad some of it was ...

I now have it mostly working, and updated to take advantage of new Python 2.2 features (given that pygtk for gtk 2.0 uses Python 2.2, there was no point in artificially limiting what constructs to use). Now I am using new style classes for all the various gimp objects (which means that issubclass(gimp.Layer, gimp.Drawable) is now true). It is almost at a stage where it could be added to the main tarball builds of gimp.
