Tidied up code, added more documentation, and the version now confirms
to some PEP standard. Because of the way configuration and arguments are
implemented, ALL the keys in configuration files should have an argument
that can change its value.
Verbose option was commented out, since it is not implemented. An
argument --print-wifi, which should print out WiFi ssid and password is
not implemented at the moment. Also, the README should be updated to
show the new changes. By the way I just remembered I didn't update the
CHANGELOG; I'll do it in the next commit. 😁
