Force-load areas with mesecon usage
This is a major speedup for large mesecon machines / structures. Force-loaded areas are stored in a file to be persistent over server reboots. By default, areas are unloaded after 10 minutes (600s) without usage, this can be customized with the mesecon.forceload_timeout setting. Please turn max_forceloaded_blocks up for better performance.
