Bug 6497: MARC URLs not showing up in details pages under normal view

Bug 6497: MARC URLs not showing up in details pages under normal view

Part one:  followup to the original patch.  The variable name for the URL itself was wrong, so despite
getting the link to show up, the href was the catalog page itself, NOT the 856$u.  Updating "MARCurl.MARCurl"
to "MARCurl.MARCURL" fixes this issue.

To test:  go to the OPAC, and see that the URL in the link is the same as the URL in the MARC

Part two:  this problem is present on the staff side, as well.  This patch implements both parts of the fix
(renaming "MARCurlS" to "MARCURLS" and "MARCurl.MARCurl" to "MARCurl.MARCURL")

To test:  go to the staff client, and check that a)URLs show up and b)they link to the URL in the MARC record
