[Delivers #48702729 #391] remove autogen from ao title

I've removed the autogen of the Archival Object title and reworked it to generate a readonly 'label' instead.  This 'label' value is used to populate the tree and the index data for this record. 

Also fixes #391 by introducing an event refreshtreenode.aspace that is triggered when the new form inserted into the page after a successful update/create generates and executes some javascript.
