Allow the authenticator to slip some authentication data down the line to

the PresentsClient which can then use it to fill in things like access
control information for the user. We could use this to replace the
UserStash mechanism we use on Yohoho, but that works so I doubt I'll do
that. However, this is needed to do things the more elegant way on future
projects, like Game Gardens.
