Subject: SCRIPTING STILL BROKEN Added comments and regions, restructured code
 Changed a lot of AppDomain junk from console from using Console.Write to
 Log.Verbose and set it to #if DEBUG All modules should now refresh their
 configuration runtime Made all logging in ScriptEngine.Common get script name
 from actual engine Renamed LSLLongCmdHandler to AsyncLSLCommandManager Added
 auto-recover with 5 sec throttle for new MaintenanceThread
