We can use the same padded plaintext across multiple numbers or attempts rather
than re-creating it every time we encrypt to a particular number.

Verified that the Alt+S shortcut isn't installed on new installs, but I
suspect that it won't fix the situation for users who have already
installed older builds, and have the Alt+S shortcut in place.

Sadly, that spacing now needs to be bigger because scrollIntoView
doesn't honor margins which overlap each other to eliminate this kind of
'too much spacing' kind of problem.

We will now always attempt to mark things unread if this method. If the
conversation's unreadCount gets out of date, set to zero, we will still
do it. If we go through the motions, and nothing is newly marked read,
we will still set the unreadCount to zero.
We queue the job because we often get a whole lot of read receipts at
once, and their markRead calls could very easily overlap given the async
pull from DB.
We also disable read receipts for any message marked read due to a read
receipt. That's a notification explosion we don't need.
FREEBIE
We mark as read everything older than this message - to clean up old
stuff still marked unread in the database. If the user generally doesn't
read in the desktop app, so the desktop app only gets read receipts, we
can very easily end up with messages never marked as read (our previous
early read receipt handling, read receipts never sent because app was
offline).

Because we only attach AttachmentViews to the DOM when they fire their
'update' event, we were subject to a race condition. If that event fired
after the final Message.render(), then it would be properly attached to
the final DOM node. If it fired early, it would end up missing from
the visible DOM entirely, attached to the old, discarded version of
the message.
This change updates our handling of a second call to loadAttachments().
Instead of bailing out if we've been called before, we attempt to
re-add our child AttachmentViews to the current DOM. But only if the
'update' event has been fired, and if their current parent node is not
what is in the DOM.
FREEBIE
To handle the same 'not quite at the bottom' case that our 30px buffer
gives us for marking messages read, we use the same atBottom() method to
determine whether we should mark everything unread. Saves the effort and
potential missed messages (due to partial pixels, etc.).
