Github RSA Fingerprint

when running cap deploy:setup, I get stuck on the gem install.

I've gotten pass this by using ssh-keyscan on the deploy user, but then I get public key errors from github.

I've tested on 1.2.2 and HEAD

Changing all the gems to use https instead of ssh solved this issue. But this is a temporary fix.
