Thumbnail style update/es

This thumbnail style update seeks to showcase our images with clean, simplified styling and captions, to highlight their beauty without distraction. It will also bring consistency with the new image galleries, image styles on mobile and most Main Pages.



El cambio en corto

 * Image border styling is removed
 * Image box background color (previously #F9F9F9) is removed
 * Image margin and padding is increased between the thumbnail and adjacent text
 * Image caption text-size is altered (to 0.85em from 0.875em) for better readability at the decreased size and to distinguish it from body text
 * Image caption text-color is changed to better distinguish it from body text (from grey #252525 to #555).
 * Magnify icon is removed (now that MediaViewer enlarges images by default)
