FR: Allow ability to forceably override value of path fills to `currentColor`

[benfurfie]

If a path has been set as a value, applying currentColor doesn't cascade. Filtering and overrriding the SVG's fill values would be a good approach to solving this issue.

@benfurfie I ran into this same issue. I'm wondering if a simple CSS fix is all that's needed here.

.fill-current * {
	fill: inherit;
}
