[Talk-GB] Key: PMSA_ref

[Andy Mabbett]

I've tidied up and updated the documentation for Public Monuments &
Sculpture Association PMSA references:

    https://wiki.openstreetmap.org/wiki/Key:PMSA_ref

and I'd be grateful if someone would cast an eye over it, not least
with regard to formatting, as I plan to do more.

It seems that the PMSA have, unhelpfully, changed their URI structure,
and that the references no longer form part of the URI.

For example, "WMbiBIxx288" is now:

    http://pmsa.cch.kcl.ac.uk/pmsa-database/6690/

Should we tag with the URI as well as the ref?
