This patch includes lots of changes to tox environment for
automatically detecting pep8 failures, which can cause python2 vs
python3 failures after install.
The following tox commands have been added
tox -efmt-check - This checks the python syntax and formatting
tox -efmt - Automatically fixes python syntax formatting that
fmt-check complains about.
tox -etype-check - check on types
tox -elint - flake8 run
This patch also changes where the default config file is located.
The new location is ~/.config/aprsd/aprsd.yml
You can now also specify a custom config file on the command line
with the -c or --config option as well.
