[f-spot/cleanup-backend: 1/23] Add the concept of sources

[Mike Gemünde <mgemuende src gnome org>]

commit aa636441854a14234feb6ffc4668f3939e837d2d
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)
