- Fix hashing of levels to get the "right" order in universe contexts etc...

- Add a tentative syntax for specifying universes: Type{"i"} and foo@{Type{"i"},Type{"j"}}.
These are always rigid.
- Use level-to-level substitutions where the more general level-to-universe substitutions
were previously used.
