With perfectScrollbar, we needed to call a function from JavaScript to
enable a scrollbar on a new element, but simplebar has a much simpler
default API one can do by using data-simplebar attributes in the HTML.
So we can delete all the scrollbar creation/deletion code.

In between releases, the following commit introduced
a bug where we agressively scroll to the top every
place we call `ui.update_scrollbar`:
092b73d0b7
The main symptoms were that the left and right sidebars
would go to the top for things like selecting a topic,
getting activity updates from the server, and resizing
the window. It was very jarring.
The recent commit looked innocuous--the root of the problem
was the original API expressed an intent to scroll to the
top, but didn't actually do it, so it was a bug in hiding.
There are **some** occasions where it's actually appropriate
to scroll to the top, mostly around search filtering, and
in those places we now call the new `ui.reset_scrollbar`
function.
This is a bit of an emergency fix, so particularly with
the settings stuff, we may get more reports of glitches here.
The important thing here is that you almost never want to
reset the scrollTop for sidebars.
We now rely on set_up() methods to call their
own module-specific versions of maybe_disable_widgets()
in the codepath for admin_sections.load_admin_section().
And then for live updates, we just explicitly call
all four modules that support maybe_disable_widgets().
This should make switching between sections slightly faster,
and it also reduces the risk of module A messing with
module B's state. (Granted, we have lots of other ways
that modules can mess with each other's state.)
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
In stream deactivation modal, make "stream_name" a template variable,
rather than patching stream name to modal header in javascript.
Add tests for deactivation stream modal.
This adds perfectScrollbar to the default streams table
because it currently is inside another perfectScrollbar which
actually makes it impossible to scroll the table normally without
enabling the perfectScrollbar library on this.
Fixes: #6391.
Using weird characters when filtering options items in these various
settings pages would throw exceptions whenever they didn't form a
valid regular expression.
We now wait to load Organization sections until you
click on the section (or virtually click by using arrow
keys).
Some of the sections are coupled in terms of their setup,
so some sections will already be loaded if you had clicked
on a related section.
This changes the layout of "organization settings" for
non-administrators such that they can view "Default streams" ("Actions"
and the form to add new default stream is not visible).
