Slack 1.2.1: a clearer Send tile, and a send target you can see

The line above the message box said "Sending as Apollo Beach → #ops" with a
Lock button beside it. The box's own placeholder already reads "Message
#ops…" and the title bar already has a Lock, so both went. Quick replies
keeps its line: it has no placeholder, so that is the only place its target
is named.

The bigger thing behind it: until a transcript was clicked, a send went to
the first channel in the admin list whether or not that channel was on the
dashboard — so a board showing only #ops would quietly aim at #general. The
target now falls to the first configured channel whose transcript is
actually up, which with a single transcript is that one. Only when the page
shows no transcript at all does it fall back to the first configured
channel.
