34aeaee672 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.

19c5d3eaad Cue user about unexpanded type aliases 
This tells the user that more type aliases are
available for expansion. For example, (Listof Number)
has the alias Number still unexpanded into the union
that it represents.

fd33584b6f 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.

a6f110893f 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.

3fd9df03f7 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.
