datach barcode reader input changed a little bit control code recalculating logic. 

now if you input full 13 or 8 digit code the control code won't be recalculated.
only if you input partial 12- or 7-digit code without control number it will calculate it.
this is done because some game uses it's own control code calc logic and need to be input as is.
otherwise it will be recalculated and won't be accepted by the game.
