 * "Patch" class to handle the change JRegistry to JForm in 1.6
 * Both classes handle Form generation, but obviously there are JRegistry functions that are not present in JForm
 * This causes function call like render() to fail in 1.6
 * The aim of this class is to attach old JRegistry functions into the JForm and allow necessary modifications to be applied on the functions
 * More functions from JRegistry could be included in the future.
 * This is a temporary solution only
