Small JAPI binding for GHC in CVS

[Mike Thomas]

Thanks Malcolm.

| Unfortunately, the module Graphics.UI.Japi.Types uses a ghc-only
| extension: deriving on newtypes for the classes Integral, Real,
| Num, and Enum.  If it wasn't for that, it would be very portable.

Woops.  I'll try and work out a way of fixng that up after I get the GNU
Common Lisp Windows installer out of the way over the coming week.

I'm a half baked Haskeller, so suggestions on how best to type the interface
are welcome.

Cheers

Mike Thomas.
