[f-spot/cleanup-backend: 12/24] Add the concept of sources

[Mike Gemünde <mgemuende src gnome org>]

commit 066a290f4e87fbaf7d8682fb46b8054fa24141e2
Author: Mike Gemünde <mike gemuende de>

    Add the concept of sources
    
    We are going to introduce the concept of sources, where a source
    is responsible for providing photos. This first commit introduces
    the ISource and IPhotoSource interface (to be extended). We start
    switching our backend to this interfaces, because that allows
    hopefully to clean up some code. (This is heavily inspired by
    banshee)
