Two things made harder to review this bit:

1. Somehow github is not playing well with the force push. I can't see all changes by navigating in a per commit basis, I keep looking at the outdate commits and the only way to see the updated ones is to see everything in one page (File Changes).

2. The commit msgs could be more helpful, since it's more going on than it's descrived :)

Thanks @ocehugo I appreciate your comments, but I don't want to spend any more time on this PR, so I'll merge it.
