Sorting jobs only by priority causes a situation where low priority jobs can get starved by a constant flow of high priority jobs.
The new formula adds a modifier to the sorting rank to take into account the number of cores the job is requesting and also the number of days the job is waiting on the queue.
Priorities numbers over 200 will mostly override the formula and work as a priority only based scheduling.
sort = priority + (100 * (1 - (job.cores/job.int_min_cores))) + (age in days)

Besides that, also take layer_int_cores_min into account when filtering folder_resourse limitations to avoid allocating more cores than the folder limits.
