When running the web admin interface with
'python -m aprsd.wsgi' the Flask app global now uses
the web_ip config entry for listening. Also disabled
debug output.
This patch starts the work to replace flask-socketio with
python-socketio so that uwsgi can be used instead of gunicorn.
uwsgi can support websockets.
Have to rework webchat command next
This patch removed the dependency on flask-classful. This required
making all of the flask web routing non class based.
This patch also changes the aprsis class to allow retries for failed
connections when the aprsis servers are full and not responding to
login requests.
