* Date input for pnForms

* returned from {@link pnForm::pnFormGetValues()} is although a string of the format 'YYYY-MM-DD'
* since this is the standard internal Zikula format for dates.
*
* You can also use all of the features from the pnFormTextInput plugin since the date input
* inherits from it.
