Push multiple updates in each update event

Refactor HostUpdatesEvent, InstanceDetailsUpdatesEvent, ModUpdatesEvent,
ModPackUpdatesEvent and UserUpdatesEvent to have multiple updates of the
entities they support in each event. This is intended to make the events
capable of syncing the entire list that they represent.
