c++: display the stack in the same order as in C

Browse Source 
Currently the C and C++ parse traces differ in the order in which the
stack is displayed: bottom up in C, top down in C++.  Let's stick to
the C order.

* data/skeletons/stack.hh (stack::iterator, stack::const_iterator)
(begin, end): Be forward, not backward.
