Event handling is now enabled by default. If the monitor cannot query the EVENTS- table (most likely because of missing credentials), print an error suggesting to turn the feature off. When disabling events on a rejoining standalone server (likely a former master), disable binlog event recording for the session. This prevents the ALTER EVENT queries from generating binlog events. Also added documentation and combined similar parts in the code.
