settings: Unbreak wifi display on tablets

In change 46af8086db0db5b41f20c9f05a5f42c182262576 the option
to enable/disable the wireless display was moved to an action
bar which ends up entirely removing the ability to enable it
for devices using Settings in tablet (multi-pane) mode.

Follow the pattern of dreamcast which correctly displays
and removes the action bar.

settings: Auto-brightness levels shouldn't fill the screen

On tall displays this ends up with a lot of useless padding
in the list.

Allow changing theme to Holo.Light without crashing

Themes that attempt to change the settings theme's parent to
Holo.Light will end up crashing wifi settings.

Themers should override Theme.Settings.Base and leave Theme.Settings.Holo
alone.  Attempting to theme Theme.Settings.Holo will result in crashes
when accessing wifi settings.

This was patch was adapted from
