[Marc-Andre Lureau <malureau src gnome org>]

commit cc5dff056bead1933276fae0fc83f859d60789e5
Author: Marc-Andrà Lureau <marcandre lureau gmail com>

    Start GNOME Shell search provider
    
    Add gnome-boxes-search-provider skeleton.
    
    With this basic form, it can already be seen by GNOME Shell, but will
    return no result atm.
