Add a real playlist naming dialog and UX flow.
This is a bit rough at the moment since theres a good amount of nuance
here. Should improve as the playlist implementation continues to grow
more fleshed out.
Unwind the picker abstraction into smaller dialog packages.
While this increases repetition, it will make the playlist dialog
implementations much less shoddy.
Refactor the music name implementation to do the following:
1. Unify normal and sort names under a single datatype
2. Handle arbitrary-length digit strings
3. Ignore puncutation regardless of the intelligent sort
configuration, as it is trivially localizable.

Refactor the weird picker god module into specific sub-impls in
playback and a new navigation package.
I cannot keep this unified. The needs are too different among each
picker. Better to keep it separate, especially in preparation for
the playlist dialogs.
