Custom css class for tooltips

Created by: alexfigueiredo

Say I want to customize a tooltip that I am using to show a validation message at a specific input in my form. It would be nice to have the ability to specify a class name for a tooltip, something like:

$("#my_input").tooltip({
    title : 'Esse CPF já está cadastrado',
    trigger : 'focus',
    placement : 'top',
    cssClass : 'error'
});

Better yet if it had styles to match warning, success, error and info.
