Fix some annoying behaviors

Incorporate PRs #8 and #9 to allow command without options to work correctly, and to allow a command to be executed with -e option (and also make the expiration times less dense)

Big thanks to @Danno040 for pulling these together

Also discovered the magic kingpin library configuration to fix the annoying behavior where any arguments passed to the command would be ingested by kingpin and throwing errors. Now any arguments specified before the profile arg are consumed by kingpin, and args after the profile are passed through to the command. No more need for --!
