Picard Tagger Script

$noop(Refactored the tagger script; Added constants and tried to make it much more streamlined

		Lines 1-2: Set constants for the date [in parentheses] and whether an album is Various Artists
		Line 3: Swap articles to the end of artist names for sane sorting
		Line 4: If not a VA compilation, prepend the date constant to the album title string
		Line 5: If there are two or more discs, prepend the disc number to the track number
		Line 6: Add the artist name to the filename for VA compilations)

$set(_cDate,\($if2($left(%originaldate%, 4),$left(%date%, 4))\))
$set(_cVA,$eq(%albumartist%,Various Artists))
