classes: Make methods dispatch on maybes. Fix a couple bugs in the implementation of maybe. classoid? is now a dumb test if an object could be a well-formed classoid; valid-classoid? tests for well-formedness. Move maybe tests. Make pprint* work better on methods.

classes: Add a check that arguments to classoids are themselves classoids. Introduce a new word-prop that makes tuple-class words classoids at parse-time so that self-referential tuple definitions with maybe{} work, e.g. TUPLE: node { next maybe{ node } } ; Add unit test. Fixes #766.

classes: - Allow methods to dispatch off union{ } and intersection{ } classes. - Add not{ } anonymous-complement syntax. - Define class-name for anonymous-union/intersection/complement and maybes, and clean up pprint. - Change maybe: foo to maybe{ foo } - Call sort-classes when making anonymous-union/anonymous-intersection classes so that they are canonicalized.
