[tracker/wip/carlosg/cli-split] tracker: Add --url argument to "tracker info"

    tracker: Add --url argument to "tracker info"
    
    We still default to nie:url and Nepomuk, as there's plenty of advice
    around about just doing "tracker info <uri>". However we don't want
    to fixate on Nepomuk here, so add an --url <url-property> argument
    that allows tweaking that.
