* generator/InterfaceGen.cs (Generate): gen the EventHandlers for sigs
	* generator/Signal.cs (GetHandlerName): kill this and split it into
	EventHandlerName and EventHandlerArgsName props instead of the ugly
	out param hack.
	(GenEventHandler): make public void and add gen_info param. open
	stream with gen_info. use new *Name props.
	(Generate): only gen the EventHandler if we're genning the container,
	not for implementors.
