Bug 11878 - Eliminate use of deprecated jQuery .toggle() method usage

jQuery's .toggle() method can no longer be used to trigger a pair of
specified functions. .toggle() can only be used to change the visibility
of an element. This patch fixes a few places in Koha where the
deprecated functionality was used.

To test, apply the patch and clear your browser cache.

- View the system preferences page in the staff client. Clicking a
  heading ("Appearance" under OPAC preferences, for instance) should
  collapse that section. Clicking again should expand it.

- View the MARC detail page for a record in the OPAC. Clicking the "view
  plain" link should display the plain MARC view. Clicking the "view
  labeled" view should return to the original view. Test in both prog
  and bootstrap themes.
