[CF-metadata] standard names to be added

[Jonathan Gregory]

Dear all

The following proposed standard names result from email threads in November
and December, initiated by Knut Lisaeter, Tony Jolibois and Keith Dixon. They
will be added next week (Monday 23rd) unless anyone has further comments.

Cheers

Jonathan
