This patch removes the "opac_option" parameter from opac-basket.pl. It
was included in Bug 25402 because the bug was dependent on 5087.
To test, apply the patch and add some items to the Cart in the OPAC.
Click the Cart button to show the cart. The pop-up window should load
correctly without errors.
