Zen: Add notification policy management api.
- Allow apps to read and modify notification policy (currently
which items are prioritized in "priority only" mode), but only
after they've been granted access by noman.
- Access to read/modify notification policy requires a token provided
by noman. Enabled notification listeners are automatically given
tokens (new getter on NLS), but any other app can also request them.
- Currently, all requests are granted.
- Also add a new change intent when the public policy changes.
