 * PART 1 - Stop restockpiling of items stored in the armory.
 * For everything other than ammo this is quite straightforward,
 * since the uniform switch code already tries to store items
 * in barracks containers, and it is thus known what the intention
 * is. Moreover these containers know which squad and member they
 * belong to.
 * For ammo there is no such code (in fact, ammo is never removed
 * from a quiver, except when it is dropped itself), so I had to
 * apply some improvisation. There is one place where BOX containers
 * with Squad Equipment set are used as an anchor location for a
 * pathfinding check when assigning ammo, so presumably that's
 * the correct place. I however wanted to also differentiate
 * training ammo, so came up with the following rules:
 *  1.  Combat ammo and ammo without any allowed use can be stored
 *      in BOXes marked for Squad Equipment, either directly or via
 *      containing room. No-allowed-use ammo is assumed to be reserved
 *      for emergency combat use, or something like that; however if
 *      it is already stored in a training chest, it won't be moved.
 *  1a. If assigned to a squad position, that box can be used _only_
 *      for ammo assigned to that specific _squad_. Otherwise, if
 *      multiple squads can use this room, they will store their
 *      ammo all mixed up.
 *  2.  Training ammo can be stored in BOXes within archery ranges
 *      (designated from archery target) that are enabled for Training.
 *      Train-only ammo in particular can _only_ be stored in such
 *      boxes. The inspiration for this comes from some broken code
 *      for weapon racks in Training rooms.
 * As an additional feature (partially needed due to the constraints
 * of working from an external hack), this plugin also blocks instant
 * queueing of stockpiling jobs for items blocked on the ground, if
 * these items are assigned to any squad.
 * Since there apparently still are bugs that cause uniform items to be
 * momentarily dropped on ground, this delay is set not to the minimally
 * necessary 50 ticks, but to 0.5 - 1.0 in-game days, so as to provide a
 * grace period during which the items can be instantly picked up again.
