Summary: Fix of variables assigned by reference in formelementtray

Initial Comment:
Liaise and xForm used:

$t =& new XoopsFormCheckBox(
$t =& new XoopsFormRadio( 

which is deprecated in PHP 5.3 (passing of objects by reference)

After correcting it, the multiple checkboxes and radio selections showed the same (last) selection.

This was caused by the function addelement in formelementtray.php:

	function addElement( &$formElement, $required = false ) {
		$this->_elements[] = &$formElement;
		if ( !$formElement->isContainer() ) {
			if ( $required ) {
				$formElement->_required = true;
				$this->_required[] = &$formElement;
			}
		} else {
			$required_elements = &$formElement->getRequired();
			$count = count( $required_elements );
			for ( $i = 0 ; $i < $count; $i++ ) {
				$this->_required[] = &$required_elements[$i];
			}
		}
	}

After removing the ampersand  from &$formElement so it is not assigned by reference anymore,  it is working now correctly
