Subject: [PATCH] Bug 25274: Don't initialize DataTable if table isn't present

This patch modifies the OPAC basket JavaScript so that a check is added
for the existence of the "itemst" table. This avoids an error if the
"More details" view is selected and hte "itemst" table isn't present.

To reproduce the error, add some items to the OPAC cart and open the
cart window. Open the JavaScript console in your browser and click the
"More details" link. You'll see an error.

To test, apply the patch and perform the same test as above. The error
should not be present. Test that table sorting in the "brief" view words
correctly.
