Title: Write cursors to TextWriter directly instead of creating strings

- Write cursor manually to the TextWriter instead of using the JsonTextWriter.
- Changed GetCursor on ISubscriber to WriteCursor is Action.
- Get rid of MakeCursor, MakeCursorFast and MakeCursorSlow since they're unneeded.
- Moved LongPollingTransport message bus logic into the transport itself.
- Removed Receive overload on ITransportConnection that was made specifically for LongPolling.
-
