When the Personalized tab is active in Discover, Show which Users are Followed

[jjeffryes]

The Personalized tab in Discover can be very confusing. To make it more clear what it is doing, at the top of the listings it would be good to show the handles (or guids if no handles are available) of the nodes the user is following, and indicate that only listings from those users are being shown.

Alternatively a message like "showing listings from X sellers", where X is the number of nodes being followed, and clicking or hovering over the message would show the list.

Otherwise if none of the nodes the user is following are online, or they aren't following any nodes, the Discover page can be blank, and appear broken.
