David Lynch 795b428477 MWNumberedExternalLinkNode: set an explicit type
This lets copy-paste between documents retain the numbered status rather than
falling back on pasting "<a>[3]</a>".

Update the part of LinkCache which selects on mw:ExtLink, so it will handle
possible multiple values in the link rel.
