Syntax error

[jareep]

When running cd /opt/alarmdecoder-webapp/ && python manage.py initdb, I receive an error:

/usr/local/lib/python2.7/dist-packages/OpenSSL/crypto.py:14: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in the next release.
