Refactor LocationSettings

- Extends BasePreferenceController in LocationBasePreferenceController
which binds preference key based on xml file instead of writing the key
in java code. Then the controller can be used in many xmls.
- Modify LocationServicePreferenceController to support only personal or
profile user.
