Improve saving strategy for bulk editor
Currently all records are reloaded. This creates problems especially with large lists.
We need a save strategy which
- only saves the records that were really changed (already implemented?) yes already implemented
- reloads only records that have been changed in the meanwhile or which are new
- removes records which have been deleted in the meanwhile
- is save in terms of session handling (no duplicate objects, multiple representation exceptions, ...)
