For longer running servers, searching the backlog can become ambiguous
since the date stamps that demarcate the messages only include the month
and day. This commit changes the behavior to include the year for
messages which are more than a year old.
If the date_row is between two messages, it tells you when the message
below was sent, but not when the message above was sent--for that you'd
either have to click on a message or keep scrolling up. This is especially
annoying when there are sometimes gap days on a particular stream (you shouldn't
assume that the message above is simply from the previous day).
This adds the date of the previous message (the time above) to the date_row.

In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
