/**
 * \brief Adds an integer range configuration item to a category.
 *
 * This function creates a new ConfigItemIntegerRange item and adds it to the specified category.
 * The item represents an integer value within a specified range, and allows the user to modify the value.
 *
 * \param cat                    The category handle to which the item should be added.
 * \param identifier             Optional identifier for the item. Can be NULL.
 * \param displayName            The display name for the item.
 * \param defaultValue           The default value for the item.
 * \param currentValue           The current value for the item.
 * \param minValue               The minimum value allowed for the item.
 * \param maxValue               The maximum value allowed for the item.
 * \param callback               A callback function that will be called when the config menu closes and the value of the item has been changed.
 *
 * \return                       Returns true if the item was successfully added to the category, false otherwise.
 *
 * @note The defaultValue and currentValue must in the specified range.
