Don't be so quick to throw the manpage in my face

This has bugged me for a long time...

@mwmiller @killerfish any thoughts on this?

I also noticed that because we're using `MooX::Options`, it auto generates a list of commands and arguments for each possible command (thanks to `GetOpt::Long`). If we went through and documented each command and all the arguments that could be a little nicer than showing the manpage because then at least I don't have to exit something to get back to my commandline.
