Oni: Provide an option to configure the command palette appearance

[badosu]

This is how it's displayed on a high DPI high, font size screen:

Maybe we could start also by making its hue match the OneDark color theme (right now the command pallet has a warm hue and the OneDark base color is cooler (more blue)).

Thanks for logging the issue @badosu ! This is very ugly. I believe it is the same issue in #713 (using pixels for font sizing), and would have a similiar fix.

The hue / colors are a good point too - I experimented a bit with using colors based on the current background / foreground colors of the vim colorscheme.

This should be addressed with PR #749. I couldn't repo the High-DPI issue though unfortunately, but I believe it's due to a mismatch with font-size pixel vs point. The change uses em sizing for Oni's UI, so that it is a derivative of the font size specified in the settings. There were lots of places in CSS we used pixels, which would be problematic.. Feel free to reopen if you're still seeing this.

I wil create an oni-git package to try and reproduce from master branch.

👍 Works great, thanks!
