Fixed ALF-4512: MLText and NULL storage problems

Browse Source 
- Synchronizing the cached values with the low-level DB keys had problems for some use-cases
   - Switching from null ML value in default locale (real null) to null value in a specific locale
   - Switching from d:any empty array to d:any empty array of empty arrays
   - other odd cases
 - Refactored the differencing code to do high-level differences
   - This makes it easier to take care of the switches between properties states
   - Sacrifices on performance when dealing with 100K multivalued properties
