Bug 3651 Follow-up, Require patron login to send shelves and baskets

The fix for Bug 4289, "Add a syspref 'OpacPublic', to hide OPAC
search-bar and force authentication on all OPAC pages" incorrectly
made some page permissions dependent on the value of the OpacPublic
setting. Some pages should require authentication no matter what.

This patch returns opac-sendbasket.pl to the state it was in before
Bug 4289, Bug 4274 notwithstanding. I have added the authentication
requirement to opac-sendshelf.pl to match.
