QIPAddressValidator

It would be a nice feature to have a premade QValidator that specializes in IP Addresses.

It currently can be done with the QRegExpValidator and something like :

le = new QLineEdit();
QRegExp rx( "((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9])
.)

(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9])" );
le->setValidator(new QRegExpValidator(rx,this));

But an optimized class would be nice.
