Previously we would just discard the results of get_old_messages,
which meant that any messages sent either while you were doing the
tutorial or that you started out with (as in the case of the CUSTOMER3
experiment) would be lost until you reloaded.

There are also one or two places we don't need to use it for security
purposes, but we do so for consistencey.

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.
