The Kohana folks removed the cache cleanup code back in

http://dev.kohanaframework.org/projects/kohana2/repository/revisions/4605

So now our cache entries don't expire.  For now, do cache expiration
whenever we render Admin > Maintenance, since that's the type of place
that users will go when they want their cache to expire anyway.
