A number of changes getting ready for a new ipcluster. * Added argparse.py to IPython/external * New reuse_furls options to ipcontroller. By default the controller will now delete all old furl files unless the -r flag i given. This is needed so engines starting up don't pick up the old furl files. * Minor logic changes in ipengine and engineconnector related to detecting errors relating to furl files.
