// 06/07/02 : JA : Added textarea and radio support. Also added ability to specify form and 'fields requird' message
// --/--/-- : AR : modified for empty required field
// 09/12/04 : JA : Updated to support 'password' type. Added automatic password validation, if another password box is found
// 02/03/09 : DB : Added extra email validation (not just checking for an '@') (Taken from the Voice site)
//				 : Now checks required and non required fields (if present). E.g. email
