Linking vraptor-brutauth to VRaptor4Version branch.

Since the branch master use VRaptor 3, what about link the plugin to VRaptor4Version branch ?
> So I'll update the version here an revert the changes of link.

please, leave the `caelum/...`, just remove the `/tree/VRaptor4Version`.

> To put VRaptor 4's code on master, it's needed to be done by an official commiter, is it ?

We can ask it for the plugin's father, @leocwolter :) Can you help us?
