Add `remove_alert_word()` function which uses the correct data flow
while removing an alert word.
`alert_words_ui.js` was structured differently from most of the other
settings. It was not using the triggers from the server for running
the success/failure handlers.
We now make it so that $('foo').addClass(whatever) and similar
functions properly return the wrapper object for chaining
purposes. We may eventually want to change the wrapper object
to automatically dispatch to the first child object, but this
should work for now.
Rationale: For the more off-to-the-side edit history view, changes
are easier to digest by highlighting deleted content in red followed
immediately by added and changed content in green.
TODO: Toggle for showing the edited messages without highlighting;
deleted content would not be shown in this view.
The floating_recipient_bar is cloned from recipient_bar elements.
The cloning created elements in the DOM with duplicate id
attributes, specifically <span id="timerender{id}">, which
contains the date of the message stream. The timerender span
will now use class="timerender{id}" instead.
Fixes#4997.
Fixes#5128.
Previously, if we had both a date and a subscribe bookend, they would
appear in one order after new messages were sent (bookend_bottom of
the top group), and another after a reload (bookend_top of the bottom
group). This makes the experience consistently a bookend_top.
Added new file to test stream sort. Specifically,
it tests the `sort_group` function's ability to put
streams into the corect pinned/normal/dormant category,
filter them based on keyword, and sort alphabetically.
We use zjquery now for testing stream_list.js, which runs faster
than the real jQuery and allows some test isolation. The nature
of the test is basically the same, but we don't actually render
templates. Instead of making assertions about the DOM, we are
now making assertions about how the stream lists get constructed
from other elements.
