Convert underscores in the href attribute to spaces in the linear model,
and back to underscores when going back to HTML. This ensures the link
targets displayed to and edited by the user look nice

This means we don't have to rely on data-rt.sHref. It also means that
we'll now be showing the canonical link target in the link inspector
rather than the link target as entered by the user, but that's fine.
Also change test to have href differ from sHref to show that we use
href.

This is ugly but makes things work again. I intend to clean this up once
we have a better attribute API
* Recognize mw:WikiLink, mw:SimpleWikiLink, mw:ExtLink,
mw:NumberedExtLink and mw:UrlLink
* Support is incomplete because we can't get to the annotation text with
the current API
* Preserve all unhandled attributes rather than special-casing data-mw
* Update remaining code using data-mw (sHref and stx extraction) to
account for the data-mw -> data-rt rename
* Update tests accordingly
