* method definitions in "child" interfaces also hide those in "parent"

    interfaces, even if they only differ in resulttype (mantis #11862)
  * fixing this required that multiple entries for the same method in a
    interface vmt are all written out (change in
    ImplementedInterface.AddImplProc)
