Alphabetical indexing support all models

Alphabetical selection (i.e.  display all the artists, albums, and songs that start with “N” for instance)

A simple wheelable 123…abc…z listing.  Example: I want to hear Manfred Mann songs…

Under artist, hit menu button, “ABC” is a selection.  Scroll to it, hit the center button and the abc…z123…(of course it wraps around) list is displayed.  Scroll to m and hit center button and all the artists who start with “M” are diplayed.

This should be selectable under all current(genre, artist, album, song, and playlist) as well as the future folder/file navigation that I’m hoping will be adopted soon.
