	* generator/ClassBase.cs (ctor): mangle hash names for sigs and props
	* generator/Parameters.cs (MangleName): handle params, null, and ref
	* generator/Parser.cs (ParseNamespace): ignore "hidden" types
	* generator/StructBase.cs (MangleName): handle params, null, and ref
	* glib/Object.cs (Equals): kill, also kill == and !=
	* sources/Gda.metadata : new, make Gda behave without hand edits
