[pygobject] Add GLib.MINFLOAT etc. and mark GObject.G_MINFLOAT etc. deprecated.

[Christoph Reiter <creiter src gnome org>]

commit 9285b23cd1b253baaf06ddd49e2f000716bbf7f3
Author: Christoph Reiter <reiter christoph gmail com>
Date:   Tue Jan 27 16:36:02 2015 +0100

    Add GLib.MINFLOAT etc. and mark GObject.G_MINFLOAT etc. deprecated.
    
    They are defined in glib, not gobject and not included in the gir;
    Similar constants like G_MAXINT64 are defined in GLib gir and marked
    deprecated in the GObject overrides already.
