[1.4.10] Bug: Train send to pick up -0 iron ore

[mrvn]

If you accidentally set the request limit to a negative number LTN will constantly dispatch trains to pick up -0 items. Might be better to show an error in that case.

I'll change thresholds to be absolute values in the next version.
e.g. -2k threshold will be treated as +2k threshold.

That will also allow negative request thresholds that are sorted nicely with negative item values making it easy to check which items are below the threshold at a glance.

Even better.

I just had a thought though. What about mixed stations where the ratio of goods is skewed? To make an extreme example what if I have cars and iron plates in a station? I might want a limit of 5 for cars but 1000 for iron plates.

I know you can't (sanely) have a limit for every good. But what about a limit counted in stacks? I might want a request limit of 4 stacks of coal (200 coal) or 4 stacks of wood (400 wood).

I decided against that a while ago.
It's easier to see what LTN is doing when thresholds are using the same unit as the circuit network which is amount of items or fluid.
