IE, Chrome, Firefox plugins: gracefully disconnect when server connection drops.
1) Plugins fails gracefully in the face of a disconnect, returning undefined instead of making lots of noise.
2) Plugins invokes hosted.html's __gwt_disconnected() method the first time the session is detected as dropped. This glasspanels the app.
