support hint was added to Translator and Parser

Examples usage help : for List {{1,2,3,!4! ?helpText? }}, for TextInput {{...|rightAnswer ?helpText? }};
As a result, creates html <div id = object._id+ _help>help!?</div> which will be used as a button;
Button appears only if there is a hint;
helpText property was added to List() and to TextInput();

Callback function for hint is not implemented!!!!;
