Apparently it isn't always the case that removal of jquery and the DOM
prevents cleanup_event_queue from being called via the postunload
hook, so add a check to avoid it being double-called.
We are seeing error on CUSTOMER4 when clearing the DOM on reload. So
now we will only clear the message list.

The reload initiation is required to run before other parts of the site
are started so that page_params will be setup correctly. This moves that
initiation out of an on ready handler to an explicit initialize call
near where the rest of the app is started.

When navigating away get_events will fail after we delete the event
queue before leaving the page. In that case we try to reload the page to
correct the problem. This happens before the page navigation is
complete, and then we reload zulip keeping the user captive. This was
only observed on on Firefox.

Previously, we saved the current_msg_list selected id and then
restored it as the home_msg_list selected id, which could result in
the home view loading to the wrong place.
This takes some already bad code and makes it even more in need of
refactoring, but it does fix a pressing bug. We should definitely
refactor both:
* the top of narrow.js
* the save/restore code in reload.js
after this, though.

The channel module now keeps track pending ajax requests and has an
abort_all function to angle all pending requests.

Chrome was showing a memory leak after many auto-reloads. Emptying the
the collections and removing the event listeners reduces the severity.
Before this change 40 reloads would would grow to about 140MB, now it
stays around 50MB.

These engagement data will be useful both for making pretty graphs of
how addicted our users are as well as for allowing us to check whether
a new deployment is actually using the product or not.
This measures "number of minutes during which each user had checked
the app within the previous 15 minutes". It should correctly not
count server-initiated reloads.
It's possible that we should use something less aggressive than
mousemove; I'm a little torn on that because you really can check the
app for new messages without doing anything active.
This is somewhat tested but there are a few outstanding issues:
* Mobile apps don't report these data. It should be as easy as having
them send in update_active_status queries with new_user_input=true.
* The semantics of this should be better documented (e.g. the
management script should print out the spec above)x.

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.
