snxtitem()/nxtitem(), for simplicity and more uniform syntax. Country
names no longer work when specifying more than one country (snxtitem()
restriction). As usual with nxtitem(), silently ignore unsuitable
items (the old code complained and failed). Don't skip powerless
countries for power c. Closes#1025607.
(set_target): Unused, remove.
members introduced in nuke.h rev. 1.19 and 1.20: nuk_plane, nuk_effic,
nuk_tech, nuk_stockpile. Make output similar to the other unit
reports while we're at it.
airburst. Leave taking nuke off the plane to caller. Use coord for
coordinate parameters.
(pln_damage): Take nuke off the plane.
(detonate): Destroy the nuke. This is required since arming doesn't
remove nukes from the nuke file anymore (arm.c rev. 1.15).
carrying it. This is required since arming doesn't remove nukes from
the nuke file anymore (arm.c rev. 1.15).
(nuk_prewrite): Properly destroy nuke. This is required since nuke
file contains individual nukes instead of stockpiles (nuke.h
rev. 1.19).
(nati, populace): Use it.
(populace, nati): Change hap, pct from float to double, because they
are used as double.
(nati): Print happiness needed with just two decimals, like the other
levels.
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.
(nukstr): Hold one nuke instead of a stockpile: replace members nuk_n,
nuk_types by nuk_type, nuk_plane. Add nuk_land for completeness, like
nuk_ship it's not yet used.
(nuke_ca): Update accordingly: replace selectors number and types by
type and plane.
(build_nuke): Update accordingly.
(ndump, nuke): Update accordingly. Output is no longer sorted by
location, and nukes in same location no longer share id. nuke's extra
columns for nuclear plants are repeated for every nuke.
(trade_desc): Update accordingly.
(cede, grab_sect, check_nuke_ok, detonate, trade_nameof): Talk about
nukes instead of nuclear stockpiles.
(arm, disarm): Rewrite, split off new disarm(). Don't remove nuke
from the nuke file on arm. Allow usual plane syntax, not just plane
number. Change second argument from nuke type to nuke number. When
plane is already armed, ignore nuke argument and rearm (broken in
4.2.6).
(tran_nuke): Update for changed struct nukstr, make as similar as
possible to tran_plane. Change syntax to match transport plane.
(player_coms): Update arm, disarm and transport accordingly.
(prnuke, nuk_on_plane): New.
(nuk_add, nuk_delete): Stockpile management, remove.
