Title: Tokeninfo

Added features to validate a token using a request to an endpoint on the Doorkeeper server at /oauth/tokeninfo?access_token=token. A token can then be validated by performing a string match on the returned results.

This feature is very similar to what Google offers for validating tokens for client side applications.

This could also be used by another API to check if a token sent to it is valid. If you have several APIs you would probably only want to use Doorkeeper as a central authentication/authorization server and have your APIs validate tokens sent in requests to them.
