The attached patch makes remove_child() available as removeChild(pos, keep).
That's consistent with getChild. Only renamed remove_child to removeChild and
added a check for validity of the pos argument.
removeChildren() will be used in input.cxx, and a lot in the upcoming
dynamic new_gui dialogs, which are aiming at replacing the hard-coded
dialogs. I'll discuss them on the list once the infrastructure is
in place. (The <hide> gui property was one part of it.)
