Subject: Add an extension to allow registering multiple interfaces of a type
 with Scene. Make the script engines check that the engine name in the
 //Engine:language comment is a valid engine and treat it as a normal comment
 if it's not. //DotNetEngine: needs to be written as
 //ScriptEngine.DotNetEngine: now, since that is it's real internal name.
 //XEngine: still works
