Feature request: Points overrides

[prophile]

It is sometimes useful to, for judging reasons, award or deduct points, often "as if" something happened. Previously we've done this by concocting false descriptions of the end state of a game which give the right result.

It would be nice to be able to explicitly do the following:

1. Add, deduct, or set (excluding the calculated value) the game points given to one team in one game,
2. Add, deduct, or set (excluding the calculated value) the league points given to one team in one game,
3. Explicitly override the ordering of who won in a game, from its calculated value,
4. Add, deduct, or set (excluding the calculated value) the league points given to one team outside the scope of any particular game.
