Inject whole access token inside of auth token instead of just the string

[dkarlovi]

In the OauthToken there's support for injecting the access token, but only the string:

FOSOAuthServerBundle/Security/Authentication/Token/OAuthToken.php

Line 30 in 37b3b9d

public function setToken($token)

It's set after the auth process:

FOSOAuthServerBundle/Security/Authentication/Provider/OAuthProvider.php

Line 111 in 37b3b9d

$token->setToken($tokenString);

But, this makes access other information from the access token (like current client, for example) impossible and workarounds like setting the client as an attribute were proposed (#81).

A way better (and simpler) solution is to just inject the whole access token. We can introduce additional methods for this (setAccessToken / getAccessToken) and provide functionality for existing methods on the fly, deprecating existing methods and removing in 2.0
