On second thought we already have support for capturing and
displaying permalinks:

        blobs.doc_med.ext_ref

This stores an arbitrary value intended to uniquely
reference the "original" from which the document was
obtained. In the case of permalink URLs those can be stored
here, of course.

I added a document context menu item "Access external
original" and a few lines of code et voila:

When the item is invoked the shell script
"gm_access_external_doc.sh" (.bat) is run. The document type
and the external reference value are passed to it so it can
figure out what to do. A hook "before_external_doc_access"
is fired, too, for more customization.

That was easy :-)
