Title: Access token formater

Deal with unnormal response of access token request.
Such as:
```ruby
{:access_token => 'haha', :remind_in => 100, :expires_in => 1000}
```
where :remind_in stands for the actual expires_in time.

Now you can set a proc when the oauth2 client initializes.
So... when combined this gem with omniauth-oauth2, it is much more convenient to deal with some not-very-standadized api provider.
