Cherry-pick fix for bug 37059 and another cherry-pick to make it possible to replace the feedback form with a link to prevent ongoing spamming of the feedback page.

   * Makes feedback form for technical problems appear only if there is not
   a link configured for techcnical problem feedback
   * Changes getFeedbackHtml() to renderFeedbackHtml() since the method
   was already partially rendering the HTML anyway. Now it renders
   all of the HTML generated in this function so behavior is consistent
   and predictable.
   * Adds htmlspecialchars() escaping to generated feedback links

   use history api to avoid problems with buggy browsers (bug 37059)
   
   window.location.replace causes a page reload on blackberry rather than
   just updating the hash. Better to just not update the hash at all on these
   older browsers
