[Gtk-sharp-list] GladeWidget attribute renaming.

[Miguel de Icaza]

Hello,

    I would like to rename `GladeWidgetAttribute' to `WidgetAttribute',
because it is already part of the Glade namespace.    Ie, currently
without using statements you end up with:

	[Glade.GladeWidget]
	Gtk.Widget blah;

    We could do this by having first a `WidgetAttribute', and allowing
the use of `GladeWidget' and `Widget' for now, but moving towards
deprecating GladeWidget in the future.

    Comments?

Miguel.
