nuk_tech, nuk_stockpile, nuk_opx, nuk_opy, nuk_mission, nuk_radius. These have no effect, yet. (build_nuke): Initialize them. (nuke_ca): Add genitem selectors: effic, mobil, tech, group, opx, opy, mission, radius. (tran_nuke): Zap mission, just in case somebody invents missions for nukes. (trade_desc): Show tech and efficiency, for consistency with other units.
