Pipe network changes to help with preventing unneeded processing.
First small batch of performance optimizations, I've removed the set background function from the code entirely, as it is a hoax for developers and it's not worth it. This will improve smoothness at the expense of some more CPU spiking.
Optimization #2, an attempt at minimizing for in world loops. They're unneeded and severely ruin performance.
Optimization #3;
More garbage collection fixes, aswell as removal of background setting.
Optimization #4;
  Statpanel stops updating for clientless mobs, reducing CPU load.
Inactivity timer changed from 10 to 30 minutes because annoyingness, it also stops kicking administrators now, if I'm correct.
Also some small tweaks.
