Continue after failure

[kewisch]

Sometimes steps fails, such as npm publish if I wasn't logged in. This means the previous steps are done, but npm publish and the github release wasn't done.

It does not seem like there is a way to "continue", e.g. skip the first steps and just run what failed. To simplify, it would be enough if I could do grunt release:1.3.0 where 1.3.0 is the existing version, and it would simply skip the git commit etc.

Thoughts?
