Merge in changes that were made for CMC.
* The "date" input field is now mapped to both "date" and
"publication_date". Previously it was only "publication_date",
which is different from what all pazpar2's other .xsl files produce,
with the result that a UI that uses "md-date" would not see dates
from CF targets. Adding "date" output as well fixed bug #3218 for
CMC, and will also fix the (presumably as-yet unnoticed)
date-display bugs in other Masterkey applications that use CF
targets. It did not remove the "publication_date" output in case we
have other Masterkey UIs that expect to see this date.
* Add support for the CF's "location" and "callno" fields.
