Merge pull request #1011 from stefanv/salted_password...
Merge pull request #1011 from stefanv/salted_password Add hashing of passwords to notebook configuration. From now on, we do NOT support plain text passwords in the notebook configuration file, only hashed ones. To create a properly hashed password, you can use `IPython.lib.security.passwd()`. Written with Mateusz Paprocki (@mattpap at github).
