Title: Makes "missing" pickleable

We had some objects using "missing" that needed pickled, but because missing's class is not accessible by name. This makes it pickleable by returning the name of the "missing" global, and there's a test verifying that the instance of "missing" returned when unpickling is the same global instance.
