JWT detection

[FranklinYu]

Currently if header has Authorization: Bearer it would say "JWT detected" (I believe the logic is here), but RFC 6750 doesn't require Bearer Token to be JWT (for example some Google API doesn't use JWT as Bearer Token). It might be better to label the request as "JWT detected" only when Bearer Token is valid JWT.
