  Log Message:
  -----------
  Optimize REPLACE for index-only items

1) We re-added cascading on SAVE/UPDATE - it seems that it can be
   safely used
2) When replacing, we simply add values to the collection instead of
   persisting them manually. It looks like the persist, although
   produces no SQL command, is particularly slow because of Hibernate
   processing.
3) We do not apply item-only modifications to main prism object
   (there's no point in doing so).

  Optimize object clone operation

There's no point in checking uniqueness when cloning items.
(PrismContainer already had this optimization implemented.)

  Log Message:
  -----------
  Improve updating shadow with large # of values

The current implementation of ADD value operation in repo is slow
for large number of values. As a test, let's use REPLACE in that cases.
