Submit on blur option

During some test I noticed users wouldn't confirm a value by pressing enter on by selecting a item with the mouse.
So I'm now submitting also "on blur", when a user presses tab or mouse clicks somewhere else.
This can be done in the 7.x-2.x-dev version by adding the following in autocomplete_deluxe.js to the blur function.

var value = jqObject.val();
if(value != '') {
  var ui_item = {
    label: value,
    value: value
  };
  self.addValue(ui_item);
}

Would be great if this could be an configurable option.
