Anders Kaseorg 719546641f js: Convert a.indexOf(…) !== -1 to a.includes(…).

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Anders Kaseorg d17b577d0c js: Purge useless IIFEs.
With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

Steve Howell c3a0a22661 slash commands: Add undo for /day and /night.
This also works for the synonyms /light and /dark.

Steve Howell 846dfb2fe4 hashchange: Extract hashchange.go_to_location().
We use this API when we want the machinery
of the hashchanged system to come into play.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
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.

Rhea Parekh d066c11b47 zcommand: Strip the slash in the backend.
The slash in command is stripped in the backend,
rather than in the client to make the client code
cleaner.
This would make client code cleaner in the slash
commands which include parameters.

Steve Howell 47b4dd6bdb slash commands: Refine /day and /night.
These two slash commands now use zcommand to talk to
the server, so we have no Message overhead, and if you're
on a stream, you no longer spam people by accident.

The commands now also give reasonable messages
if you are already in the mode you ask for.

It should be noted that by moving these commands out of
widget.py, they are no longer behind the ALLOW_SUB_MESSAGES
setting guard.

Steve Howell 4b2e8b83c4 slash commands: Add /ping command (via zcommand).
This adds a /ping command that will be useful for users
to see what the round trip to the Zulip server is (including
only a tiny bit of actual server time to basically give a
200).

It also introduce the "/zcommand" endpoint and zcommand.js
module.
