Implemented first draft for cover art:
- Cover art is downloaded after a release is found on musicbrainz via
coverartarchive and stored in internal storage.
- For a start cover art is loaded synchronously, as a pragmatic proof of
concept
ReleaseListAdapter: Using a threadlocal dateformat in order to increase
performance/efficiency
Improved new releases notification for android < 4.1
Switched back to use "exact" repeating when scheduling the released today service, because it didn't seem to work on android 2.
Android 4 is using inexact repeating implicitly anyway
Implemented display of album art on the released today notification (android >= 3 only)
Fixed a possible NPE when no artists are found on the device
Implemented asynchronous loading of images using Android Universal Image
Loader
Removed redundant set up of UIL memory cache
Updated proguard to get along with new libraries coverartarchive-api and
universalimageloader
Improved performance of scrolling with images in ReleaseList view by
pausing image loader on fling.
