Add color configuration for icons

It's also worth pointing out that the svg icons are hardcoded to use CSS variables if available (e.g. --color1) that are likely to have collisions because they are so generic. It would be better if these could be prefixed to avoid unintended collisions.

The default colors for the social networks come from the companies directly, so I don't want to change the default.

I was trying to find an example module where there is configuration for a fill. SVG is not something I have a lot of experience with, so I would need something to base it on.

Per @mandclu's suggestion, the variables now contain a prefix of "bss-" so you have var(--bss-color1) through var(-bss-color14). With this change, you can add the colors you would like in your css file:
:root {
--bss-color1: #2b6a94;
--bss-color2: #fff;
--bss-color3: #cddc39;
--bss-color4: #f60;
--bss-color5: #489951;
--bss-color6: #3a559f;
--bss-color7: #0076b2;
--bss-color8: #0084ff;
--bss-color9: #bd081c;
--bss-color10: #157efb;
--bss-color11: #ff4500;
--bss-color13: #3b445c;
--bss-color14: #000;
--bss-color15: #25d366;
}

I've added this to the README file that will be released with version 5.0.
