[2.1#1] Option to set the color only to current tab and navbar

[C2N14]

First of all, thank you very much for this add-on it is exactly what I've wanted since forever

I'd like to be able have the option to just color the current tab and navigation bar instead of all the UI as shown bellow (top is how it is now and bottom how I'd like it to be):

just use:

  const backgroundColor = `rgba(${color.r}, ${color.g}, ${color.b}, 1)`;
  const textColor = `rgb(${textC}, ${textC}, ${textC})`;
  let colorObject = {
    sidebar: backgroundColor,
    sidebar_text: textColor,
    sidebar_highlight: backgroundColor,
    sidebar_highlight_text: textColor,
    tab_selected : backgroundColor,
    tab_text   : textColor,
    toolbar_field_text   : textColor,
    bookmark_text   : textColor,
    toolbar_field_border   : textColor,
    toolbar_field     : backgroundColor,
    toolbar     : backgroundColor,
    tab_line    : textColor,
    toolbar_bottom_separator : backgroundColor
  };

But I won't need this till #22 is solved.

Your idea is amazing and makes a lot of sense, exactly because that "nav + tab" has to do with the site and the "background" equals to other tabs.
