[PATCH] First pass at a banshee provider

[Don Smith <dcsmith gmail com>]

Attached is a first pass at a banshee provider.
I've basically copied the f-spot provider and modified it to banshee's
db. This is my second python contribution, and my first attempt to deal
with conduit. As I don't have a music player, I've only used the test
audio sync. Files from the selected playlists are transcoded and placed
next to the originals with an extension mp3Test.
