Generate A-Z menus in the tagtree

this adds a new command %byfirstletter

%byfirstletter "custom_track" "Track A to Z" "title"
^ command       ^menu name     ^menu title   ^subitem

need a better name for subitem btw..

this patch also allows us to tell when we are in the BFL menu
by checking customaction == ONPLAY_CUSTOMACTION_FIRSTLETTER
we then enable spelling of the letters in the menu
it spells Numeric too but that shouldn't matter with the upcoming voice patch
