Implement InCall overflow button.

- If there are more than 5 items (for a specifically identified case)
collapse extra menu items into an overflow menu.
- Construct/update menu, with appropriate click/dismiss listeners.
This will happen every time something with the call buttons is
updated, but I thought it was better to continue to track state in
the presenter, rather than the fragment.
- Add strings for associated menu items.
