Guild challenge ameliorations

The Guild Challenge has been a major enhancement to the game and significantly improved gameplay. However, the format is sub-optimal, leading to far too many draws in each challenge.

I would therefore propose four alternatives to make them more fun:

1. Remove the match bonus for guild challenges - it's unfair that only the challenging side can use it, and unless challenges against a team are limited, it would be too expensive to extend to the challenged team.
3.. Limit the number of games allowed to be played to 10 challenges per team, especially if match bonus is left as it is.
4.. Score the challenge according to the number of games actually won by each team.
