AF Transformer sync functionailty

1. AF Transformer should be able to sync changes made in the source AF Database: if an element is added, deleted or edited.  For the deletions there should be a way to select the behavior: delete an object from the target database, place it under a different hierarchy, rename or do nothing.  2. It would be also helpful to have an additional AF property in AF - deletion flag. A power user will be reviewing a list of elements flagged for deletion and will be making a decision - delete, rename, move or do nothing (similar to functionality in the connectors admin page). 3. Changes (especially deletions and edits) should be logged with different level of details based on the debug level specified.
