Fix up union/intersection operations
Previously the union/intersection operations didn't work when you tried to
select/project/sort/drop/whatever on them. Now they just automatically
introduce a subquery, which means that they can be used in other operations
automatically. (There is a potential for a minor decrease in query speed, but I
think it's worthwhile to maintain the abstraction.)
