* generator/*.cs: add DefaultValue prop for obtaining a sane value when we need to return a value but something bad has happened such that we can't get a real value. Needed for iface signal marshaling, among other places we're partially working around it now. svn path=/trunk/gtk-sharp/; revision=86157
