If we have removed a stream from the home view, and our pointer
that we load from the server refers to a message that is no longer
visible, we don't want to error out but rather select the nearest
message to our previously selected one.

Messages are now selected on a MessageList, which triggers a
message_selected event that other parts of the code can listen for.

Previously we would select the first message in the block. Now, we
only do that if a message that is selected will not be in the
resulting narrowed view. If the selected message will be in the
narrowed view, we select that message once narrowed.

I kind of expect this to work, and hopefully this'll help with
people getting stuck on the "Settings" page in the tutorial.

Most of them are just typos or funny punctuation, but this also adds
the word "above" after "You and Humbug Tutorial Bot" since otherwise
the user might try to click the text in the message body and be
confused.

Right now the MIT realm has pretty bad UI lag with 1,200 messages loaded. We
need to fix the root problem, but this commit at least makes reloading the page
a satisfactory remedy.

Here I have a sketchy but functional framework for dealing with
all of the async stuff that a tutorial requires, and an early
draft of what such a tutorial might look like.
I could probably go and remove the first-run message, but I'll
keep it around for now in the unlikely event that something I
haven't anticipated goes wrong in starting up the tutorial.

The idea here is: part of the onboarding tutorial is going to
be you talking to the tutorial bot and it talking to you, from
our Javascript.
The reason it's driven by Javascript is that then in principle we can
do nice stuff like making popovers appear in places to point things
out to you, whereas if we were to do it strictly server-side, doing so
would be a lot harder.
The downside to doing it in Javascript is that you don't get any of
the Markdown rendering, since that happens on the server. So instead
we add this call where you give it a message, and it responds by
having the tutorial bot send you that message.
I don't think there are any security concerns here because
(1) The bot only messages you -- so you can't use it to make someone
else think that the system is telling them to do something
(2) If there were an issue associated with having the server parse
arbitrary Markdown, you could just trigger the issue by sending
a message yourself.

The defaults are quite large for a small site like ours where on
server down means an outage (e.g. only check every 5 minutes and then
require 4 failures before we alert the admins).
