Logistics bots should cancel job when request is canceled

[Harkonnen604]

Case - I order 100 steel furnaces to a requester chest (or character logistic slots). In a second I think these should rather be electric furnaces. There are other examples when some item was added by mistake. Anyway, bots that have already started moving toward me will bring and drop it anyway. Proposal - when bot arrives at request-chest-or-character it drops an item only if it will not overwhelm current logistic request of that item (being 0 if item is no longer on the list). If request is overwhelmed due to stack bonus - just drop what was requested, and drop the rest to nearby storage chest. It would also be nice if bots check if their tasks are still actual periodically, so they cancel their jobs before they fly half a base recharging on the way.
