Original commit message from CVS: registry handling changes read up on it in docs/random/thomasvs/registry if interested net effect should be transparent; ie. it will keep on working, but will be more flexible than before. Testing with garnome seems to work now. Should probably be rewritten completely, together with plugin loading, but only after we spec it out ;) It's a bit messy.
