expiration.

Added a token check to the services. It's checks if a given token can be
mapped to a user.

Added a method to set the account details and to logout. The account
details can only be modified if a valid token is passed, too. The logout
just removes the user with the given token from the database.

AccountDetails had some (de)serialization problems. Fixed the method
with a Jackson Mixin: AccountDetailsMixin.

The CustomObjectWrapper has been extended with the AccountDetailsMixin.
