+ Restored the double arrow glyph on redirection board status icons. This one only adds 31 gzipped bytes, which is way better than doing a 'proper' new icon. Also, the technique can be reused to add other glyphs to new classes, and it allows me to remove the color filter (-15 bytes), which I wasn't sure I was going to keep because it's not portable. Yes, the glyphs aren't portable either, but I think it's semantically better to reposition them, or hide them, than to play with filters which may still be relatively confusing to CSS users.
