* Replaces form input elements of class "button" with an      *
* anchor tag that can be styled, which when clicked submits   *
* the form.                                                   *
* Expected HTML structure is as follows:                      *
*   <div class="formbutton">                                  *
*     <input class="button" type="submit" value="caption" />  *
*   </div>                                                    *
*                                                             *
* Suggest that the class "formbutton" has display:inline set. *
