[plt-scheme] gtk 2 bindings for mzscheme in the works

In case anyone else is working on GTK 2 bindings for MzScheme, we should
compare notes...

I have many of the fundamentals (GObject, type-safe enum values, GLib
signal callbacks, marshalling both ways, main loop) appearing to work as
a shared-library extension, and a "hello world" program appears to work.

An "alpha" quality release will probably happen once I automate
generation of the bulk of the bindings and address a few suspected GC
issues.
