[gnome-photos/wip/rishi/filter-freeze: 2/4] Turn the PhotosTrackerController sub-classes into extensions

commit e505a40b4cbfd3852c6f28b6d4673cb75e4f95cf
Author: Debarshi Ray <debarshir gnome org>
Date:   Wed Oct 7 19:11:03 2015 +0200

    Turn the PhotosTrackerController sub-classes into extensions
    
    This will let us freeze and thaw all the TrackerControllers without
    having to manually maintain the list.
