4dd2b66d2b generalize fomega ty= to avoid specific types; add tests 
- fixes fomega bug where kind annotations were not being compared
- fix subst bug: must tranfer props (ie types) when replacing an id
- add exist tests to check proper subst in ty=

- move same-type to define-syntax-category

2278adcf95 replace provide/requires with "extends...except"/"reuse...from" forms 
- introduce basic define-typed-syntax instead of define-syntax
- add fomega3 --- same as fomega2, without the duplication
  - app and lam are both types and terms
  - arrow is both type and kind
  - same tests as fomega2
