Title: Added some events

Check it, yo:

$('#someinput').mask("99/99/9999", {
'onKeyPress': function(event) {
// sum codes
},
'onKeyDown': function(event) {
// sum codes
},
'onBlur': function(event) {
// sum codes
},
'onFocus': function(event) {
// sum codes
},

// Opposite of completed. Fires if valid input but not completed
'incompleted': function() {
// sum codes
}
});

The callback happens after the the end of the functions that alter the buffer and whatnot. Just look, you'll get it.
