Configurable Nukes & ICBMs

Makes most/many aspects of the atomic bomb configurable, and affected by quality, as well as allows for the weaponization of rocket-silos. Allows for custom payloads created from almost any ammo or capsule item, as well as introduces dedicated warhead payloads (atomic, "Rods from God", Jericho, Mjölnir), ICBMs (Intercontinental Ballistic Missiles), IPBMs (Interplanetary Ballistic Missiles), and ISBMs (Interstellar Ballistic Missiles). Why shouldn't rocket-silo rockets be used offensively?
