make hiding of initial namespace optional
It is by design that names loaded by startup files, etc.
are hidden from things like `%who`.
But this behavior is pretty surprising, especially since
ipython -i script.py
and
%run -i script.py
have different behaviors with respect to the hidden namespace.
Since the current behavior was added at the request of @fperez,
I left the default behavior unchanged,
but added a flag to disable hiding initial variables.
