Fixing minor bugs in IPython.kernel....

Fixing minor bugs in IPython.kernel. * Regular expressions now using raw strings in launcher.py * Directory permissions on cluster directory handled properly. * A raw ipcluster start will now create cluster default and add the default config files. * Config files updated to use raw strings where appropriate.
