"Details" in tuner mode

Perhaps using the "details" button on the Rio remote should bring up something useful in Tuner mode. I believe that there's RDS information that we don't currently use - it would be nice (or simply cool) to see the AF lists, for example, even though the tuner doesn't yet[1] use them automatically.

[1] Just a reminder that AF and TA handling are at the top of my wishlist...
