Description of problem:
The W3C HTML Validator reports three duplicated id attributes in HTML pages generated by RH Bugzilla (TOKEN, USEFUL-LINKS and LINKS-ACTIONS).  The HTML standards require that id attributes are unique in a document.  As these are not unique they should be a class rather than an id.

Version-Release number of selected component (if applicable):
4.2

How reproducible:
Always

Steps to Reproduce:
1. Open http://validator.w3.org/check?verbose=1&uri=https%3A%2F%2Fbugzilla.redhat.com%2F
  
Actual results:
Validator reports three errors of the form: ID "FOO" alreadt defined.

Expected results:
Validator reports no errors.

Additional info:
The W3C Validator does not report these errors for http://bugzilla.mozilla.org (though it does report other errors).
