Queue tab: running and pending prompts with who queued them

The server records who queued each prompt (and the tab's name, sent by the
client) and publishes queue items with the stats. Cancelling someone else's
prompt or clearing the queue needs Admin. Tabs: Live, Chat, People, Queue,
Server, Admin.

 **Live** shows the tab on screen: whether it is live, who else is in it, and buttons for **Snapshot** and **History**. For a private or unsaved tab it says why it is not live. Below that is the list of **live workflows**: those someone has open right now, with their folder and the people in each one. Open any of them with the arrow. The Files tab marks live files with a green dot.
 
+**Queue** shows the run in progress and the ones waiting, each with the workflow's name, who queued it and when. The button on a row stops or removes it: your own runs, or anyone's for an admin.

 **People** lists who is online and which workflow they are on. The eye button *follows* someone: it jumps to their tab and keeps your view on theirs until you click or scroll the canvas.
