- Added a activity-alias pointing to displaySettings as top level
setting item.
- Refactored all preference logic in DisplaySettings into
PreferenceControllers. During fragment onAttach it installs all
controllers, and during onResume it updates preference state. Each
controller listens to its own preference change event.
