* covers lookup reworked, now should much more accent the higher resolution without impact on reliability, the tradeoff is somehow slower processing in batch modes; can be overriden by setting user storage value image_lookup_quality_accent to always/never
+ added support for covers lookup by CD TOC on Musicbrainz, requires the Edition lookup by CD TOC script installed and enabled + user matches defined for related collage/better pages (batch processing support)
