Allow segregation of multiple users of CoverArtCache.

* Provide a QObject* requestor pointer when calling requestCover. In
  practice this can be any number you want it to but it is particularly
  useful for the requestor class to pass a pointer to itself so it can
  compare the signal it gets to itself.
* Provide the original CoverInfo request.
