Add generic URI support

Hey Vladimir,

I noted that AuthorizationCodeGrant constructor at https://bitbucket.org/connect2id/oauth-2.0-sdk-with-openid-connect-extensions/src/973a78d67f6368e065d8683ad9f025672afe7ff1/src/main/java/com/nimbusds/oauth2/sdk/AuthorizationCodeGrant.java?at=master takes in URL object for redirect_uri. This would not work if someone wants to use URN.

Wouldn't it be better if the API used URI object instead of URL?

Thanks, Kanishk

AuthorizationCodeGrant is now URI compatible, see commit bf509b1.

Completed with commit 0d8b6a4, all request + UserInfo classes have URI support now.
