Move rocket silo to production tab

[DaveMcW]

Please change the subgroup for the rocket silo item from "defensive-structure" to "production-machine".

The rocket silo produces rocket parts and space science, it does not have any defensive benefits.

Maybe to new category "rocketry", all rocket ingredient parts also to this category.
