Move 'Swap volume buttons' option to 'Buttons' menu

- no one would expect to find a volume buttons option under
  Settings>Display & Lights>Rotation
- other volume buttons options are already under Settings>Buttons
- the feature actually does not depend on 'Auto-rotate screen' option,
  it depends on screen orientation which can change also by other
  means than sensor driven auto rotation - orintation change enforced
  by top app, by dock, by keyboard slide...
- title changed to 'Reorient volume buttons' (to hint at orientation)

Settings: Use meaningful titles for gamma controls

There is good anecdotal evidence that the values we modify relate
to specific modifications (contrast, brightness, saturation and the
like) of the display, this change allows us to define descriptive
headings.

Bluetooth: Remove out of range devices after ScanComplete

Change to remove device from UI when Bluetooth of remote
device is off or not discoverable anymore. Without this
change a device that discovered previously is available
in available devices list always, though the remote device
is not discoverable anymore. The current change updates
available devices list on scan complete removing the
devices that are available in cached devices and are not
disvorable anymore.

This reverts commit 1b652eb600ad7b4a769ad495bbb7eb4c6ab82fb2.
