[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 60a0f001a5f18ceac2525deadf38816aa70a1fe0

    source-dialog: properly update edit page top widgets
    
    Build URIs for files and remote sources,
    hide things for local calendars, etc. The
    only major missing piece of the puzzle now
    is GOA itself.
