Proposal: Add Request.prototype.setHeader()

[indexzero]

@mikeal Been playing around with filed and request in conjunction with a Rackspace Cloudfiles client and I realized that adding Request.prototype.setHeader()would create a really elegant:

  var filed = require('filed'),
      request = require('request');

  filed('path/to/some/file.mp3').pipe(request({
    method: 'PUT',
    uri: 'http://uri.to.cloudfiles.com/container/file.mp3'
  });

Cloudfiles (and S3 I believe) expect incoming headers content-type and content-length which filed will set automatically for http.ServerResponse objects, but not for Request objects. Adding Request.prototype.setHeader() here and a minor change in filed would do the trick.

Thoughts?

we talked about unifying this API in core as well but never finished it.

i'm all for this going in to request.
