Fix icon validation to check currentColor in actual fill/stroke attrs

The validator used a simple substring search for "currentColor" anywhere
in the SVG file. This meant icons with currentColor only in Inkscape
editor metadata (e.g. bordercolor="currentColor") would pass validation
while rendering as black. Now checks that currentColor appears in actual
fill=, stroke=, or style fill:/stroke: values.
