* generator/InterfaceGen.cs: generate Adapters for consume_only ifaces
	too.  This seems unusual, but is primarily to produce at least one
	'generic' implementation of every interface and a GetObject method
	so that the marshaling code can always return an object which
	implements the interface, even if no public object wrapper exists for
	the underlying c GObject type.
