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.
