/**
 * Construction macro for a #CargoSpec structure.
 * The order of arguments matches the order in which they are defined in #CargoSpec.
 * Some macros are used to automatically expand to the correct StringID consts, this
 * means that adding/changing a cargo spec requires updating of the following strings:
 * - STR_CARGO_PLURAL_<str_plural>
 * - STR_CARGO_SINGULAR_<str_singular>
 * - STR_QUANTITY_<str_plural>
 * - STR_ABBREV_<str_plural>
 * And the following sprite:
 * - SPR_CARGO_<str_plural>
 *
 * @param bt           Cargo bit number, is #INVALID_CARGO_BITNUM for a non-used spec.
 * @param label        Unique label of the cargo type.
 * @param colour       CargoSpec->legend_colour and CargoSpec->rating_colour.
 * @param weight       Weight of a single unit of this cargo type in 1/16 ton (62.5 kg).
 * @param mult         Capacity multiplier for vehicles. (8 fractional bits).
 * @param ip           CargoSpec->initial_payment.
 * @param td1          CargoSpec->transit_periods[0].
 * @param td2          CargoSpec->transit_periods[1].
 * @param freight      Cargo type is considered to be freight (affects train freight multiplier).
 * @param tae          The effect that delivering this cargo type has on towns.
 * @param str_plural   The name suffix used to populate CargoSpec->name, CargoSpec->quantifier,
 *                     CargoSpec->abbrev and CargoSpec->sprite. See above for more detailed information.
 * @param str_singular The name suffix used to populate CargoSpec->name_single. See above for more information.
 * @param str_volume   Name of a single unit of cargo of this type.
 * @param classes      Classes of this cargo type. @see CargoClass
