90b149dc46 Fix union merging 
Trying to merge (and thus resolve) applications of struct
types would cause infinite looping on type instantiation
if the struct type used both a union and recursion.

d5c62424f8 Fix types of system etc for new keyword arguments. 
This requires extending the ->optkey type constructor to support rest
arguments, and fixing the keyword function type generation code.

Testing is still limited because there's no parsing for such types.
That will be handled in a later commit.

c2f5b31e96 Expend printing fuel in all branches 
This makes (:type (Number -> Integer)) produce
(Number -> Integer) instead of expanding at the first name.
Combined with expansion cues, this makes it easier for users
to expand the relevant parts of types.

664a370a1b Cue user about unexpanded type aliases

has the alias Number still unexpanded into the union
that it represents.

b35e0fd138 Cut off type printing with :type at one level 
Makes types print nicer with :type in most cases.
Previously, the printer expanded type aliases as much
as possible. Now, it defaults to a single level of expansion.
A later commit adds a #:verbose option to show the entire
type.

20f546110b Refactor subtype.rkt not to use exceptions. 
Matthew suggests that using exceptions for failure
in the implementation of `subtype` is a performance
problem.  This commit removes all use of exceptions
for failure in subtype.rkt, replacing it with the
standard Racket #f/value option.

Extensive use is made of the `subtype-seq` form,
which is basically do-notation for the subtyping
monad.
