Show change of winrate bar

[kaorahi]

This patch imports one of my favorite features from LizGoban. The change of the winrate bar is shown as the green (= good move) or red (= bad move) rectangle.

Are there more suitable colors for Lizzie?

I think it's an interesting feature.
The win rate bar of lizzie will be displayed when Nihon Ki-in broadcasts live on youtube, but I think that viewers can enjoy it more by using the version with this function.

I would just like to mention one question that I have.
The image you attached shows a red rectangle to indicate how bad a move White made, but because it is on top of the black bar, it seems to intuitively recognize that Black made a bad move.

better ideas are welcome :)

As the above design seems to confuse some users, I modified it so that Lizzie shows just the previous winrate with a simple gray line. I expect this will not disturb your eyes.
