Added reconnecting-websocket.js to automatic reconnect the websocket if the connection is lost. Usefull for mobile devices that go to sleep after a while. Changed mon_fermenters to use websockets instead of polling. Fixed wrong temperature color ranges on the fermenter monior. Increased the websocket receive buffer to 2048. In cannot overflow, but larger messages are chunked and the application does not handle these split messages. Needs termferm 0.9.9 or newer.
