Added zen settings messages and calls preferences.

- Made ZenModeSettings and ZenModeBehaviorSettings a DashboardFragment
- Switches in ZenModeBehaviorSettings all have their own preference controllers
- Instead of a dropdown, messages & calls have their own pages & preference controllers
- Added basic turn on/off DND button in settings (dialog not yet implemented)
