making cli options unixy
methadone-magic  got rid of cli option starting with --no

methadone magic :
If you provide a cli option --abc, methadone converts it to {:abc =>
true, "abc" => true}.
Only for cli options starting with 'no', it returns a false value. e.g
--no-power-on => {:"no-power-on" => false, "no-power-on" => false}. This
reads wrong in code.
