Bug 19608: (QA follow-up) Fix redirect on localization modal

This patch makes two minor corrections:

1. The item types localization modal redirect problem has been fixed by
   excluding the anti-clickjack code from executing in the footer.
2. The sidebar menu highlighting script has been modified to correctly
   handle the clone-rules page.
