Almost functional patch approval

All of the mechanisms for submitting a patch, viewing patches and approving/rejecting patches are just about done, all that remains is some DB work on an "edit patch" page. Once this is complete, we will put up a live demo on the project's home page. Also in the works is some documentation explaining exactly what our plans are for this. We're waiting for the SVN server access to put the code up, I'll try to get an update into CVS in the meantime.
