Add naming submenu for the edit screen wherein title, subtitle, artist and their
transliterations can be changed
Remove the top-level keys for same actions
Make edit screen submenus shortcut-key friendly
the full title when sorting.
Also noticed that a lot of string copying is done during the ABC sort
(and it's call to GetFullTitle)-- optimizing this away may make in-between
songs go much faster...
(These should have a common base class, but that can be done later;
I'm doing this to make it a bit more manageable so I can add the
new couples format to these.)
