Release 1.4.4

+ Fix a minor bug causing ``bin/gong`` to send the enable password when
  it shouldn't.
+ Client connectings (such as those made by ``bin/load_acl``, for
  example) will now raise an error when it is detected that an enable
  password is required and one is not provided.
+ Added SSH support for confirmation prompts

  - Added ``'[confirm]'`` as one of those prompts

+ Added ability to specify remote port for NetDevice objects

  - Add defaults in settings.py for SSH (SSH_PORT) and Telnet
    (SSH_TELNET) ports
  - Added documentation for SSH_PORT and TELNET_PORT in settings.py

+ Bugfix when passwords are passed in to make sure they are not unicode
+ Gong will now mark a device as enabled when auto-enable is detected.
+ Fix prompt patterns to include optional space and hard line-endings
+ Pin pytz<=2014.2 to fix unit tests for time being (no pun intended)
