From 9bbbea5160ae7690e2abed21fae48c1189cd0c82 Mon Sep 17 00:00:00 2001
From: RJ Ryan <rryan@mixxx.org>
Date: Mon, 27 Oct 2014 22:05:51 -0400
Subject: Improve connection between WCoverArtMenu, WCoverArtLabel, WCoverArt,
 and DlgTrackInfo.

* Remove copying of changed cover art into the folder (temporarily?).
* Mark all user-generated change events as USER_SELECTED.
* Remove reliance on CoverInfo::trackId in a couple places.
