Auto walk-over for odd players

[itsisak]

If there are an odd number of players, the one left over will be paired against himself. Then that player should automatically receive 1 point.

There was also a bug when we tried setting the result to "DRAW", which should give both of the players 0.5 points, and since both the players in that match is the same person it should result to 1 point. In theory this was supposed to be a good enough solution.
However what happened was that the player received -1.5 points. (which should not be possible since we never subtract points....). This resulted in that the admins manually gave 1 point to that player. Not good.

This should also be better displayed that is just a walk over, it could cause confusion.
