[2.0.12 Space Age] Rocket Silos request items even if rocket not ready

[Karamel]

Rocket silos request items for sending to orbiting platforms even if they don't currently have a rocket ready. This is a problem, because if you are feeding construction parts via belts then it can easily happen that upstream silos hog all construction materials to build rockets which can't be used for this delivery because it's already reserved by the downstream one. In the worst case scenario this can lead to indefinite delay if other space platforms keep arriving. Basically, you have to limit the number of silos to make that the bottleneck to keep orbital logistics working, which is pretty counterintuitive.

A simple fix would be a checkbox to let the silo to only be available for automatic deliveries when a rocket is ready.
