[FIX] Loot spawn issues & Server FPS (Somewhat)

* [FIXED] - Loot Cleanup has now been fully resolved. Old loot piles will now be cleaned every 60 minutes and no players within 250 meters(WIP). (Server performance boost)

Previous value was 60 (Seems no one changed this). Changing this to 3600 improves server performance. FPS is still low, but in game FPS drops and action delay has been significantly improved.
