Alphabet grouping for All Artists view

[ac16161]

Possible lead: I removed the tagoption all.ignore.sort={The} and the alphabetical listing for All Artists came on in Kazoo. I just noticed I have some contributing artists where instead of the artist tag being "The <Artist name>" the tag is "the <Artist name>", i.e. there is no capital T in The. Could this contribute to the problem or is this coincidence? I shall investigate further.
