Add an Edit button to the notes on the waitlist.

It is so annoying to click to read the note, then have to click away, click edit, then click in the note area, then type the update to the note. 90% of the time we need to update the note immediately after/while reading it. 99% of the time nothing else about the waitlist entry needs updated (I honestly can't think of a time that I ever changed a waitlist entry outside of updating the note)
