Moved hidden items back to original position

Moved hidden fields back to the bottom where they originally were...the
original problem I needed to solve was in the
utilities/include_payment.htm file
Div closing tag changed to LI closing tag

Bad HTML - it should be a closing LI tag, not a DIV. This was causing
problems in rendering, and cutting the FORM block short.
Updating validation and submit button logic for Issue #51

Removed the validity.js functionality on this page and replaced it with
the verificationlib.js functionality, since that's what the other pages
are using. This fixed the problem in Issue #51
Moved jquery.validity.js script to top of main template

Some of the forms are using validity.js to validate the forms and place
the code in the content template (e.g., dues payment, as reported in
Issue #51). Thus, the script tag for validity.js needs to appear before
the content tag in the WMT.
