Add in 5 second delay between flushing updates when only a single user is editing a document. As soon as an update is received from another user we switch to sending updates immediately again so there is no latency between collaborators. The logic applies to individual docs, so two users can be editing different docs and will still buffer updates since they will not affect each other.
