Game output log

I was randomly exploring in Creative when the game stopped working. The watchdog crash is from ModernFix, and references the Crab code for adding the Jukebox listener in the server thread, and the object being waited on there is also mentioned in the Sound Engine thread. I've disabled Crabs temporarily to see if the hangs stop.

Gonna close in favor of #4714 since that has more people (which also all have Smooth Chunk Save and Better Chunkloading installed...)
