Made OrderedDict sector_queue, should speed up chunk loading
Dequeues are not good at searching through (with world.delete_opposite_task)
or for removing entries midqueue.
OrderedDicts are dicts that remember their insertion order during iteration
Also, by having a custom queue for sectors we don't need to use *args, **kwargs
and move the function around. We change sectors 100's of times a second, so...
Run through the queues multiple times per tick when possible
