Rule presets - British Official

The British rules (as laid out by the British Mah-Jong Association) are a sort of a mixture between European and Australian rules. As Australian rules, they use Flower and Season tiles, limit the number of Chows to one (but unlike Australian rules, without allowing exception for a fully concealed hand) and apply a Goulash deal with jokers and Charleston after a drawn deal. Also, losers are rewarded for having a calling special hand.
