Update spectrum.css

If the user is printing from a WebKit browser (Google’s Chrome or Apple’s Safari), we can force the printer to render the colors as seen on screen (i.e. force any background images and colors to appear on the printed page).

example:

@media print and (color) {
   * {
      -webkit-print-color-adjust: exact;
      print-color-adjust: exact;
   }
}
add brazilian translation
property removed to force background images and colors
