[Feature] Setup list colors for specific board.

[Wanzyee]

Is your feature request related to a problem? Please describe. I have different board backgrounds for identifying them quickly by window view and tab icon. The suitable highlight colors are different, and the lists of different boards are not always named in the same rule.

Describe the solution you'd like As title lol... let a board settings able to optional override the global color list.

Describe alternatives you've considered I'm using "Pro for Trello" extension, too. I could manually use its color to override Strelloids's. Thank god it's owrk, but I think it's better if you can support this natively.

Additional context None, thanks for your great extension.
