is only ever used by the PresentsServer. Also determined that we need to explicitly let Guice know that CrowdServer provides the PresentsServer "interface" and so on down the line. I also think that each concrete class needs to be marked as @Singleton though I need to confirm that. Based on how annotations work, that's how it would be easiest to implement, so we'll assume they're not doing extra work on the backend to make our life easier. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@5154 542714f4-19e9-0310-aa3c-eee0fc999fb1
