PR Overview
This PR adds the selector message. It depends on the #5, so old commits can be ignored in this PR (I'll cherry-pick the new ones later).
Example
I implemented an example to show the advantages of using
selector_response. You can read it here: https://gist.github.com/aron-bordin/97ca4233b5a304cd1466c5322b358cc6It's the same spider developed here: http://gsoc2016.readthedocs.io/en/latest/quickstart.html#source-code but it doesn't requires any HTML processor.
You pass the css/xpath filter in the request: https://gist.github.com/aron-bordin/97ca4233b5a304cd1466c5322b358cc6#file-dmoz-py-L21 and just use the resulting data: https://gist.github.com/aron-bordin/97ca4233b5a304cd1466c5322b358cc6#file-dmoz-py-L34

WIP
This PR needs to be tested and implemented in the helper packages. So please, let me know if this is a good feature. If so, I'll implement the tests and implement it in the helper packages.
