Form_Dropdown doesn't unset label

[alexsancho]

Forge Form_Dropdown html_element method should unset label like other input elements

    public function html_element()
    {
	// Import base data
	$base_data = $this->data;

        unset($base_data['label']);

	// Get the options and default selection
	$options = arr::remove('options', $base_data);
	$selected = arr::remove('selected', $base_data);

	return form::dropdown($base_data, $options, $selected);
    }
