Configurable task queue size.

The task queue size should be configurable. Servers can easily have more than 256 legitimate tasks to run - an example is loading the area around spawn when that area has lots of computers, leaving some of them "half on."

I'm testing changing it to 256000 (instead of 256) on my server to see what other effects it could have. It does seem to fix the "half on" bug.

The task queue has increased substantially in the next version, so hopefully this should not be a problem. Also, in my opinion the size of a queue is something that is internal and shouldn't be exposed to the end user - but dan may feel differently.

Just a question. Is the task queue the same as the event queue?

I don't know.

I had to decrease it to 1024 as it caused several seconds of computer lag at 256000, possibly caused by something spamming the queue?
I'm hoping 1.42 has better queue management if that's the case.
