gtk version stuff

[Kevin Ryde <user42 at zip dot com dot au>]

A bit of filling in the gaps for the gtk version numbers.

I propose taking gtk-major-version and gtk-minor-version from the
global variables rather having values in gtk.scm.  Not that they'll be
anything except 1 and 2, but just to ensure guile-gtk exactly reflects
what libgtk says about itself.

        * gtk-support.c (sgtk_init_gtk_support): Add gtk_major_version,
        gtk_minor_version, gtk_micro_version, gtk_binary_age,
        gtk_interface_age.
        * gtk-1.2/gtk.scm (gtk-major-version, gtk-minor-version): Remove.
        * gtk-1.2.defs (gtk_check_version): New function.
