v1.44.0 — Cookie Banner: policy link stays whole; close button opacity and icon

• Cookie Banner: the privacy policy link at the end of the message no longer breaks between its words. When it does not fit, it moves to the next line whole. (#61)
• Cookie Banner: two settings for the close button, defaults unchanged (#62):
  • X opacity: 0.7 as before; 1 shows it at full strength. On hover it is always shown in full.
  • X shape: the × character in the banner font, as before, or a bold drawn icon that looks the same in every font and follows X size and X colour.
