[dancer-users] Help with the dancer2 command

As best as I can explain it: 
- dancer2 on its own doesn't have enough information to do something, so it shows you a help page to point you in the right direction. This is the equivalent of just asking for help with dancer2 -h

- dancer2 help gen or dancer2 -h gen or dancer2 gen -h are all ways for invoking help on a subcommand (in this case, gen)

This is consistent with other CLI suites that implement subcommands, and how App::Cmd (the framework the CLI is built on) expects to work.

I'm not saying it's perfect, and I am *very* open for suggestions for how we can improve the end user experience. And as I have a few projects involving the CLI coming up, it's a good time to address them. But this in fact how it is expected to operate. 

Hope this helps!
