Bug 757503: Player scores now reset at match start, as with team scores.
Created Score::reset() method and refactored Score a tad.
Created resetPlayerScores and sendPlayerScores functions in bzfs.cxx.
sendPlayerScores takes care of broadcasting a number of players' scores;
Called from playerKilled and resetPlayerScores.
Created Score::reset(). Created bzfs.cxx:resetPlayerScores() function. Refactored a little.
Applied to SVN, Thanx!
