Status bar date/time actions (quick settings)

Separate clickable actions for the time and date on quick settings pulldown

We added a setting panel view to the quick settings pull down on tablets
in order to to facilitate our quick setting edit button.
This panel should work the same way as the panel for the notification
shade.

Bring this in line with https://github.com/AOSPA/android_frameworks_base/commit/135a1d48b924950d822e506be1a7c01833171d88
