By default, a SpinBox's value should be unlimited, (or as close as we can get to that,) and then the GML or code can impose a limit if needed. This saves the developer from entering an arbitrary "big" max value when they want the value to have no maximum. I've audited the use of SpinBox and added `min: 0`, and removed a `max`, where appropriate. All existing SpinBoxes constructed in code have a range set explicitly as far as I can tell.
