Bug 29932: Use localStorage instead of cookie for bibs_selected

Bug 29932: Use localStorage instead of cookie for bibs_selected

This patch replaces the use of the jquery.cookie.js plugin in the
"Browse selected records" feature. The feature is modified to use
localStorage instead of cookies.

To test, apply the patch and go to Administration -> System preferences.

 - Enable the "BrowseResultSelection" system preference.
 - Perform a catalog search which will return multiple results.
 - On the search results page, check the checkbox for a number of
   titles.
 - Click the "Browse selected biblios" button in the toolbar.
 - You should be directed to the detail page for the first title you
   checked.
 - Clicking the right-arrow in the sidebar should take you
   through each one of your selected titles.
 - When you click the "Results" link in the sidebar you should be
   returned to the same search results set and the same titles should be
   checked.
 _ If you uncheck those titles and reload the page the checkboxes should
   remain unchecked.
 - If you log out of the staff interface the "bibs_selected" item in
   localStorage should be deleted. See, for example,
   https://developer.mozilla.org/en-US/docs/Tools/Storage_Inspector for
   information about viewing local storage.
