Updated scraping code so that artist names are HTML decoded prior to matching.
Album names are now normalized to improve matching on album names which contain accents
Cleaned code so that artist and album strings are handled consistently.
Updated artist and album info grabbing to ensure that stored details use the values from the track rather than those returned from allmusic.com
Revised last fix to improve results
Merge remote-tracking branch 'remotes/upstream/master' into 1.3Final_ADDON3_TV_Music
