fixed bug in expansion of expressions in interaction environment
...
where id->label was prematurely interning identifiers in the
environment. Now, there is id->label/intern that does that and it's
only used when an identifier's type is resolved and not at other
times (like in free-id=? and bount-id=?).

fixed minor bug in syntax-case where the wraps and marks of
...
top-marked wrapped syntax objects were incorrectly combined.
E.g., it used to be that:
(syntax-case (datum->syntax #'foo #'(x y)) ()
[(x y) 'shouldntmatch] [_ 'ok])
yields shouldntmatch; it's now ok.
