Make all transactions available

Sometimes the strategic move can be to spend more money on a different player, rather than less money on the wrong player.
We need to make these strategic moves available through the UI.

To make up for the explosion in combinations, we just have to get rid of the options that result in the same money for each neighbour.
As long as we give the same amounts, we don't care whether it's for wood or clay.
