refactored builtin type

this is done to avoid repeating all the arity checks all over the place.

fixed quoting behavior
...
previously it was impossible to do the following:
(define dave (quote (x y z)))
dave
the interpreter would incorrectly try to evaluate the (x y z), because
there was no quote level being recorded, and it was seen as being the
same as a regular sexp.
