Currently, users of this package cannot pass in verify options for the jsonwebtokens module as shown here:
https://www.npmjs.com/package/jsonwebtoken#jwt-verify-token-secretorpublickey-options-callback

I have resolved this issue but am unfamiliar with source control and how to make a pull request.
The modified index.js for can be found here: http://pastebin.com/kibMGb11

Users now need only to pass in a verifyOptions object in the options object for the module.
Example:

    server.auth.strategy('jwt', 'jwt', true,
        {
            key: secret,
            validateFunc: validate,
            verifyOptions: {
                ignoreExpiration: true
            }
        }
    );

I also exported the JWT.sign method so now users of the package do not need to have specific requires for it in their project.
