Settings: Battery saver settings sub-page. 

New battery saver settings page, accessed via
the power usage settings overflow menu.

The settings page has a master switch to toggle
battery saver mode, feature disclosure text,
and a preference to configure the automatic
trigger level.

Remove developer checkbox now that this option
has a real home.
