Tim G L Lyons bb854ec772 Modifications as suggested by Nick Hall:
* Remove inheritance of Citation from RefBase, using source_handle filed instead (similar to  the way Family objects store mother and father handles) (also use the set_ and get_reference_handle functions more consistently)
* Use get_citation_list instead of get_citation_references (more consistent with the way notes are handled)
