Bug 21813: In-page JavaScript causes error on patron entry page

This patch removes a block of JavaScript from memberentrygen.tt which
was being included in the page before jQuery is loaded. This causes a
JavaScript error.

To test, apply the patch, regenerate CSS, and clear your browser cache
if necessary.

 - In Administration -> Patron categories, confirm that you have two
    patron categories with different default messaging preferences
    defined.
 - Go to Patrons -> New patron
   - Create a new patron using one of the categories with messaging
     preferences.
   - Confirm that when you switch the category selection to the other
     patron category, the patron messaging preference checkboxes are
     changed to the default for that category.
     - A "Loading" indicator should appear above the checkboxes to show
      that an operation is in process. It should disappear when new
      default prefs are loaded.
   - Manually change one or more patron messaging preference checkboxes.
   - Switch the patron category again and confirm that you are prompted
     to confirm resetting the preferences to the default for that
     category.
 - Perform the same set of tests when editing a patron.
   - Defaults should not be loaded during the edit process.
 - Confirm that there are no other JavaScript errors in the console.
 - Test again with EnhancedMessagingPreferences disabled.
