Making board snapshot

[loloof64]

Adding the ability to take a snapshot of the board, in a PNG image.

The user selects the target path.

Available in play mode as well as in analysis mode.

Maybe a drawback is worth mentionning : I've not prepared a placeholder for the translations.

Besides the linter errors, there's 2 issues:

• It doesn't work on Windows: "Error: Attempting to parse an unsupported color function "color".
• It doesn't work with SVG board images. Most of the board images are PNG, but a few of them (such as the default one) are SVG, and they're not rendered by html2canvas.

Replacing html2canvas with the fork html2canvas-pro fixes the first issue, but not the second one.

I've tried replacing html2canvas with dom-to-image and it seems to work on windows and with svgs. I haven't tested on linux yet.

Thank you, so I'll make changes locally and test on linux.
Is there a way to pull those changes in my local copy ? I'm using Github Desktop but I can also do it from terminal.

I've found how to pull changes from Github desktop.

It works on Linux.
The only drawback is that the saved image does not keep the circles and arrows. But maybe that's not so necessary.

As for the linter, I may try to fix those errors.
