[Building Sakai] request for review: KNL-498, get last event time for a user

[Nuno Fernandes]

+1 patch looks good!

You should check the query on a Sakai db with millions of entries in
SAKAI_EVENT and SAKAI_SESSION (typical on production environments) as it may
have some performance impact !

Great feature!

Thanks,
Nuno
