v2.0.0: second rocket, no console-fed parts

The second rocket launched with every rocket part built by the base and fed to the silo by chests and inserters, no console-fed parts. Honest caveat: the silo and the last techs came from the earlier assisted v1.0 run, whose purple and yellow science packs were console-fed. Fixes this release: planner crash on a locked recipe, unpowered oil pumps, destroyed boilers, steel feed, a silent fuel-supply path bug, gas priority for plastic.
