* Adds the ability to have a thread efficient long poll service (such as the eventqueue)
* If this doesn't melt the Http Server, this will significantly reduce the number of threads in use on regions with many users. * Adds AddPollServiceHTTPHandler, and RemovePollServiceHTTPHandler to BaseHttpServer * Generic enough to be used for many long poll services, not only the EventQueue.
