* Implemented merge Citation

* Updated merge Sources
* Implemented undo-redo for citations (revision 18069 had only added citations to the undo-redo list, not acted on that types of element)
* Fixed embedded lists for some of the object type editors that were done in Rev 18069
* Modified EditCitation so the source parameter is optional
* Added svn properties for all /src/Merge/merge*.py modules
* Added support for EditCitation from backreflist.py
