troggle/media/feincms/jquery.treeTable.js
substantialnoninfringinguser 3784eb9720 [svn] - Remove feature (admin JSON / XML downloads) which won't work until we have django 1.1 installed (works on my SVN version, but not on seagrass debian package version).
- Copy feincms media to project so that we don't have to serve it separately. Also useful because we may want to customize it.
