Build  22
Added “Show Favorites”  & “Show Silenced Callers” toggle button to make
it clearer which callers are silenced when you have a ton of contacts
and most are in your favorites or vica versa.
The Silent list includes any contacts not in Favorites list, and also
Favorite that have all their notifications disabled.
The Silenced list only displays icons for silenced Favorites to make
them and it visually distinct.
- Moved Add button to Nav bar.
