Namespace is wrong for Laravel 4

[jnbdz]

I have been trying out this repo with Laravel 4.

I was able to make it work. But I had to modify some of the code.

Everywhere this "\OAuth2[...]" appears I had to add "\League" to it to finally get the code to work.

I don't know if this is a mistake or it's just Laravel 4.

Anyways, it's an easy fix.

I presume this has been taken care of with @alexbilbie's documentation updates?

This was fixed before #74 I vote to close this issue.
