Bug 24621: Phase out jquery.cookie.js: Basic MARC editor

This patch removes the use of the jquery.cookie plugin by the basic MARC
editor for setting two interface preferences: Showing MARC tag numbers
and showing MARC documentation links.

To test, apply the patch and open the basic MARC editor.

 - From the "Settings" menu, select the "Show MARC tag documentation
   links" link. This should toggle the display of the "?" link next to
   MARC tag descriptions.
 - Reload the page to confirm that your selection has been saved.
 - Perform the same test with the "Show tags" menu item.

You can also follow the changes to the cookie using the browser's
developer console. Look for cookies named 'marcdocs_***' and
'marctags_***' (where *** is the borrowernumber of the logged-in
user) and confirm that the value of each flips from "show" to "hide" and
back.
