Make ContactPreferences use SharedPreferences instead of System settings (5/5)

* Move constants that originally lived in the framework into ContactsCommon
* Use SharedPreferences instead of System settings to persist preferences
* Use a SharedPreferenceListener to monitor changes instead of a content observer
on system settings
* Move DisplayOrderPreference and SortOrderPreference into ContactsCommon so that
it can be used by Dialer
* Create base DialerSettingsActivity in Dialer, and make GoogleDialerSettingsActivity
extend it
