Ed Sanders 22d1908bd4 Update reference lists and inline numberings automatically.
The easy part is getting the correct numbers from the InternalList
and generating the ordered list HTML. The tricky part is connecting
up the events to make sure the renumberings/list generations are
triggered when required.

InternalList can emit an update event on document transaction, which
triggers the renumbering/relisting if any references have been
added or deleted during that transaction.

ve.ce.MWReferenceListNode also listens to changes on the
InternalListNode (i.e. changes to the contents of the references)
and always triggers a rebuild.
