New theme 'yasnaya' by @ParmuzinAlexander
As discussion: #385

Because the 'board1.png' already as the default board, so use the 'board7.png':

1. Allow user turn on/off the border by option 'show-border', default is turn off.

2. And new theme options are added:

"winrate-stroke-width": 2,
"minimum-blunder-bar-width": 3,
"comment-background-color": [0, 0, 0, 200],
"comment-font-color": [255, 255, 255, 200],
"comment-node-color": [0, 0, 255, 200],
"winrate-line-color": [0, 255, 0, 200],
"winrate-miss-line-color": [0, 0, 255, 200],
"blunder-bar-color": [255, 0, 0, 200],
"blunder-winrate-thresholds":[-30,-20,-10,-5,5,10],
"blunder-node-colors":[[255,0,0,200],[0,255,0,200],[0,0,255],[255,255,0],[0,255,255],[255,0,255]]

3. and font setup:
   "ui-font-name": "Wawati SC",
   "winrate-font-name": "Wawati SC Bold",
   "font-name": "Wawati SC",

PS: above the options are effective for both config.txt & theme.txt

@ParmuzinAlexander
About these new options, do you have some better suggestion?

@zsalch
Everything is fine except the font in the screenshot. But I see normal font with "Wawati SC". Font should be clear and understandable.
P.S. Ideally, I would like to remove border from board. Lizzie copied this from Sabaki, but this is a bad. The border is nowhere in other programs or the real Board. But you've already done a lot of work, I don't want to ask for anything else.

The wawati SC just a test font, current the theme 'yasnaya' does not setup a font, it will use default font.

The board border seems to have been there, not this change.
No board border, do you mean like following? Maybe we should allow the user to remove all the borders, because now almost all panels have it.

@zsalch
It's perfect!

I replaced board7 to the original texture. But it is not very important, visually they are the same.

I added a default config option: theme: "default" so that it can easily be changed.
