Update to Swiss Tie-break Algorithm

CHALLONGE! now uses the Median-Buchholz system for breaking ties in Swiss tournaments. A "tie-break score" column will now be displayed in the results table which shows the sum of a player's opponents' scores, with the best and worst scores discarded. Should players be tied by score and tie-break score, they are sorted based on their records relative to one another. Seed breaks up any remaining ties.
