* glib/ObjectManager.cs, glue/type.c: If there isn't
an exact match for a C GObject class (i.e. BluecurveStyle), walk up the gobject type hierarchy until we find a type that we do have a wrapper for, and return that. This means that you'll always, worst-case, end up with a GObject. * glib/Value.cs, glue/value.c: Added default constructor to GLib.Value() that creates a new value with a type of INVALID, and changed the glue function to not call gtk_type_init if INVALID is passed. svn path=/trunk/gtk-sharp/; revision=7994
