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.

http://rails.lighthouseapp.com/projects/8994/tickets/1199-helper-test-generator

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
