/**
* Form text box hints.
*
* This plug-in will allow you to set a 'hint' on a text box or
* textarea.  The hint will only display when there is no value
* that the user has typed in, or that is default in the form.
*
* You can define the hint value, either as an option passed to
* the plug-in or by altering the default values.  You can also
* set the hint class name in the same way.
*
* Examples of use:
*
*     $('form *').textboxhint();
*
*     $('.date').textboxhint({
*         hint: 'YYYY-MM-DD'
*     });
*
*     $.fn.textboxhint.defaults.hint = 'Enter some text';
*     $('textarea').textboxhint({ classname: 'blurred' });
