Hack to support Oxford DOIs in 956 fields

ScholarsPortal MARC records put Oxford DOIs in their 956 fields instead
of 856; let's use both of them and hope that no other records use a 956
that doesn't actually resolve.

Also, if the URL is for books.scholarsportal.info, identify
ScholarsPortal as the platform.
