tugboat create --help actually creates "--help" droplet

[kojiwell]

Version:

Tugboat 0.2.0

Issue:

I sometimes stupidly execute tugboat create --help which will actually create a droplet. This is obviously my bad, and I know the right command is tugboat help create. However, it would be nicer if it generate an error instead, because it costs money even though it's a small loss.

Thanks!

Using --help is my first instinct as well.

I've had a go at this, it doesn't generate an error but just displays the help text as you would expect help create to.
