Helper generator

Hi guys,

I've recently submitted a patch that modifies the generators that create helpers (like controller, resource, etc) to generate helper tests as well.

Pratik suggested to also add a --no-helper parameter to those generators cause very often he ends up removing the created helper.

I think it makes sense cause I usually remove em too.

I've also been thinking that a parameter like --no-test might also be helpful in case you're using an alternative testing framework or say create a controller for a static section of the site (which is less likely of course) Anyways, I'd appreciate any feedback.

Thanks, Eugene
