Safely clean up the cover art manager
This patch changes 3 things:
(1) Cover art is assumed false until read true
(2) We no longer clean up the CA manager if the feature isn't
enabled. This will keep us from having NPEs since an enabled feature on
start always translates to an object. Plus, since its defaulted to off,
this makes calling stop() before start() safe for cover art.
(3) The stop and start functions are now synchronized so there are no
race conditions inviting rare errors.
