Bug 20600: (follow-up) Move template JavaScript to the footer

This patch moves the ILL requests template's JavaScript to the footer.

Also changed:
 - Removed unused jQuery checkboxes plugin
 - Some <input> tags have been corrected to be self-closing.
 - Title tag has been corrected
 - Table row limit of 10 has been removed in favor of accepting default
   used elsewhere.

To test, apply the patch and follow the original test plan for this bug.
Everything should work as expected.
