TPAC: Display full publication info

In both the results table and record summary, we were failing to display
the place of publication - which is critical information for people
trying to track down the right edition or constructing a bibliography.

Grab the place of publication, and then reconstruct 260abc (avoiding
another XPath iteration and giving ourselves the ability to enhance the
schema.org microdata at the same time).
