Icon to indicate High-Resolution Content

Add an icon to indicate if the source file is high-resolution - e.g. no icon under 88k, 88k to 192k as high-res, and above 192k as very high res. Display on Player Screen and beside title in song lists. Perhaps dim the icon a little if the current Output mode is not sufficiently high-res for the file contents?

Technical limitations:

• requires clarification on the icon placement(s)
