add stlc+rec-iso files; rename record files; start exist
...
- previously forgot to add stlc+rec-iso.rkt and tests
- rename files with records (eg stlc+var, stlc+rec+sub)
- use "reco" to avoid confusion with recursive types ("rec")
- start exist.rkt --- existential types

add fomega2.rkt
...
- fomega2 is the same as fomega.rkt, except tyapp, tylam, and => are removed
- instead, #%app, \lam, and -> serve dual purpose at both term and type level
