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.

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.

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.

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 .

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.

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 .
