Authorization authorizationPeriod and publishedPeriod Support

[jateeter]

The authorizationPeriod and publishedPeriod must:

1. be supported correctly in the authorization class -> they be initialized from values obtained from the scope string(s).
2. must also be used properly in the exportFilter class -> publishedPeriod must be used in conjunction with publishedMin and publishedMax (and all) within the export process
3. the authorization (and associated access_tokens) must be disallowed or destroyed when the authorizationPeriod expires (possibly using RFC 7009).
