Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
ES and TypeScript modules are strict by default and don’t need this
directive.  ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Anders Kaseorg f3726db89a js: Normalize strings to double quotes.
Prettier would do this anyway, but it’s separated out for a more
reviewable diff.  Generated by ESLint.

Steve Howell 1f156230b0 refactor: Clean up alert_words API.
We add these two functions to the API,
so that we no longer have `alert_words_ui`
using private data from `alert_word`:

    alert_words.has_alert_word()
    alert_words.get_word_list()

And to initialize the data, we have a proper
`initialize` method that is passed in only
the parameters that it needs from `ui_init`.

(We also move the step of deleting `alert_words`
from `page_params` to the `ui_init` module.)

Because it's a bit less cumbersome to initialize
`alert_words`, we now just it directly in the
node tests for `alert_words_ui`.

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.

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.

Harshit Bansal a13535ff1f alert_words: Don't muck up rendered HTML content while munging.
Prior to this we were also performing highlighting inside HTML tags
which was wrong and causing weird behavior. Like, for example, if
someone added `emoji` as an alert word then any message containing
both emoji and alert word was rendered with a jumbo emoji.

Fixes: #4357.

Harshit Bansal d5ab8ac1e1 alert_words: Remove the `page_params.alert_words` after initialization.
We remove the `page_params.alert_words` since `alert_words.words`
is the sole source of alert words. Use of `page_params.alert_words`
could lead to bugs when alert words are updated since it is not updated.

Tim Abbott b25562ca1d Add and use util.is_current_user helper function.
Previously, we were checking if a particular user was the current user
in dozens of places in the codebase, and correct case-insensitive
checks were not used consistently, leading to bugs like #502.
