Add collection, campus and repository data to solr doc.
Start to use vcr, to remove crazy mocks.
Repo & campus URI data filled in.
Partway thru vcr implementation, but changing to httpretty

httpretty is a bit more explicit and the actual responses from the vcr
are not really optimal for testing.
Switch to httpretty, works nice. Need to remove my mocks eventually.

TestHarvestOAC_JSON_Controller works now with httpretty

Removed my custom http mocks. Using httpretty now.
