Depends on : http://review.cyanogenmod.com/#change,13743

Cleanup unecessary resources and use global ones
  - This fixes the duplicate id issue currently causing apn's to be un-editable

Bring the ui aspect of the preference up to speed with ics
 - Use ics highlight / layout...etc
 - Use fragments

Patchset 5 : Remove theme for ApnEditor
             Use static access for variables
Patchset 6 : Launch apn editor internally as a fragment
	     Replace deprecated managedQuery with CursorLoader
