[tracker: 10/30] tracker-extract: Turn into a full-blown miner

[Carlos Garnacho <carlosg src gnome org>]

commit 814de784c9aa875163003ddf255d30b45ddf8233
Author: Carlos Garnacho <carlosg gnome org>
Date:   Tue Jan 7 22:21:25 2014 +0100

    tracker-extract: Turn into a full-blown miner
    
    TrackerExtractDecorator is put in use, replacing TrackerController as
    the master of TrackerExtract. .service and .desktop files are added as
    appropriate so tracker-extract is recognized as a miner, handled by
    tracker-control, etc...
