Getting "headers already sent" when fetch action returns error.

[tobice]

I think the problem is at this line: https://github.com/yahoo/fetchr/blob/master/libs/fetcher.js#L108

In case of error, status 400 is set and response body is sent, but the function just goes on and four lines later it tries to send the response body again.

By the way, could you change it that the whole err object could be sent back instead of the general "request failed" message?

Yikes, yeah that needs to be fixed.

And yes, we need to clean up the error logic here.

That was quick :) It's good to hear that someone's working on that.

We'll get the return fixed immediately and @mtscout6 is working on related status code changes in #17

The bug should be fixed in version 0.3.2.
