* Fix embedded SVG fill attribute
SCSS darken/lighten functions may not return a color value, but a color
name like "white". See following example:
https://www.sassmeister.com/gist/c41da93b87d536890ddf30a1f42e7816
This patch will normalize $color argument to FFFFFF style.
I also changed the function name from "url-friendly-colour" to
"hex-color", Because...
1. The name "url-friendly" is not meaningful enough to describe what it
does.
2. It is familier to me using "color" rather than "colour"
