Require ~/.aprsd/config.yml 

This patch completes the migration to using a config.yml file.
~/.aprsd/config.yml is now required and all options for callsign,
imap, aprs user, passwords are in the config.  If there is no existing
~/.aprsd/config.yml file, then the app will output a sample config
and exit.

This patch also adds a global logging facility that allows logging all
commands to aprsd.log as well as stdout.  You can disable logging to
stdout by adding --quiet on the command line.  You can specify the log
level with --loglevel INFO.  By default the log level is DEBUG.

This patch also updates some formatting issues and small refactoring
to ensure that the logging facility and config is read prior to starting
any network connections and/or services.
