New plugins

Hi,

I just wanted to notify you of a couple of plugins I wrote for rhythmbox
recently. Both basically to help me clean up an over inflated music
collection. Developing them has been a bit of a learning experience as
it's been my first experience using python, gtk or rhythmbox so I hope
they're not too amateurish.

Anyway, I've stuck them up on github in the hope they'll be useful to
someone else.
