Returns the Ship ID for any built ship associated with a given build slot. Valid slot IDs are 0 to 23 inclusive. (Note: -1 may be the HQ slot.) -1 is returned if the ship is not placed (an unconstructed build outline counts) or if the slot ID is invalid. -2 is returned when there is no ship build button at the given slot.
