[glade--]glade-- compile error and fix

[Alexander Barton <abarton mindspring com>]

My build of glade-- from the CVS repository failed under gcc version
2.96.  ostream &operator<<(something) in const_contained_iterator.cc
references const_contained_iterator::stack which is declared private.  I
added a friend declaration which seems to have satisfied the compiler. 
Diffs below.

Thanks,
Alexander
