Improved support of CActiveForm::error method for input widgets.

Added support for disabling AJAX or client validation for specific form elements.
This is achieved in the following manner: $form->textFieldRow($model, 'email', array('errorOptions'=>array('enableAjaxValidation'=>false, 'enableClientValidation'=>false)));.
Please note that using this paramtetrs makes sense only if a corresponding validation type is enabled for entrie form.
