Music Events

Fixed alGenSources error caused by reloading resources and when the mod attempted to play the next song of a playlist while the game was paused (with play_when_paused = true of course).

Optimized the hell out of the mob events and the mod's entity detection system, no longer drastically increasing the CPU time on high render distances. You should notice about 70% to 80% less CPU time on the mod's debug screen, very rarely going beyond 0.6ms and completely removing the CPU time spikes of 25.0ms to 75.0ms that caused stuttering.

In my case i run 13 different mob events, along other 28 non mob events and i haven't gotten any major CPU time increases in the few hours that i've tested it.
