FEATURE: Add Google Universal Analytics v4 as an option (#11123)
Per Google, sites are encouraged to upgrade from Universal Analytics v3 `analytics.js` to v4 `gtag.js` for Google Analytics tracking. We're giving admins the option to stay on the v3 API or migrate to v4. Admins can change the implementation they're using via the `ga_version` site setting. Eventually Google will deprecate v3, but our implementation gives admins the choice on what to use for now.

We chose this implementation to make the change less error prone, as many site admins are using custom events via the v3 UA API. With the site stetting defaulted to `v3_analytics`, site analytics won't break until the admin is ready to make the migration.

Additionally, in the v4 implementation, we do not enable automatic pageview tracking (on by default in the v4 API). Instead we rely on Discourse's page change API to report pageviews on transition to avoid double-tracking.

FEATURE: Upgrade analytics.js to gtag.js (#10893)
Per Google, sites are encouraged to upgrade from `analytics.js` to `gtag.js` for Google Analytics tracking. This commit updates core Discourse to use the new `gtag.js` API Google is asking sites to use. This API has feature parity with `analytics.js` but does not use trackers.

FEATURE: automatic dark mode (#10341)
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets. 

This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.

ed95a6005b FEATURE: screenreader landmarks for main, suggested topics
In order to avoid a boatload of attributeBindings, I moved the root
element of the suggested-topics component into the template. Also,
autoformat their hbs files.

Testing info: https://www.scottohara.me/blog/2018/03/03/landmarks.html#using-screen-readers-to-navigate-landmarks

Additionally, flag modals with aria-modal=true to avoid the screenreader
accidentally escaping the modal. There's no need to ever toggle the
attribute to false, because we display:none the modal root when it's
closed.

3189dab622 FIX: correctly remove authentication_data cookie on oauth login flow
Additionally correctly handle cookie path for authentication_data

There were two bugs that exposed an interesting case where two discourse
instances hosted across two subfolder installs in the same domain
with oauth may clash and cause strange redirection on first login:

Log in to example.com/forum1. authentication_data cookie is set with path /
On the first redirection, the current authentication_data cookie is not unset.
Log in to example.com/forum2. In this case, the authentication_data cookie
is already set from forum1 - the initial page load will incorrectly redirect
the user to the redirect URL from the already-stored cookie, to /forum1.

This removes this issue by:

* Setting the cookie for the correct path, and not having it on root
* Correctly removing the cookie on first login

* FIX: Some errors and clean up in confirm-new-email

It would throw an error if the webauthn element wasn't present.
Also I changed things so that no-module is not explicitly
referenced.

* Remove `no-module`

Instead we allow a magic comment: `// discourse-skip-module` to prevent
the asset pipeline from creating a module.

* DEV: Enable babel transpilation based on directory

If it's in `app/assets/javascripts/dicourse` it will be transpiled
even without the `.es6` extension.

b57e108e84 FEATURE: improve email change workflow
- Show old and new email address during the process
- Ensure correct user is logged on when attempting to make email changes
- Support reloading a page during the email reset process without resubmit
of form
- Improve tests
- Fixed issue where redirect back to site was not linking correctly in
subfolder setups

Internal refactor of single action into 4 distinct actions that are simpler
to reason about.

This also removes the step that logs on an account after you confirm an
email change, since it is no longer needed which leaves us with safer
internals.

This left me no choice but to amend translations cause the old route was
removed.

3b16eb7abb FIX: Confirm new email with backup codes enabled
This is a fix for this bug:

https://meta.discourse.org/t/-/133185?u=blake

where rails would throw a missing template error when trying to confirm
a new email address when you had two factor backup codes enabled.

Apparently this feature broke during this commit:

68d35b14f4

when a partial that contained a lot of javascript was removed most
likely because it didn't comply with our Content Security Policy, so as
a fix I rewrote the previous js functionality without using any
javascript and then added a spec to verify that the correct backup code
form is displayed when that page is loaded.

FEATURE: Add site setting to show more detailed 404 errors. (#8014)
If the setting is turned on, then the user will receive information
about the subject: if it was deleted or requires some special access to
a group (only if the group is public). Otherwise, the user will receive
a generic #404 error message. For now, this change affects only the
topics and categories controller.

This commit also tries to refactor some of the code related to error
handling. To make error pages more consistent (design-wise), the actual
error page will be rendered server-side.

FEATURE: Use full page redirection for all external auth methods (#8092)
Using popups is becoming increasingly rare. Full page redirects are already used on mobile, and for some providers. This commit removes all logic related to popup authentication, leaving only the full page redirect method.

1cebe7670a FEATURE: Allow embedding to ignore HTTP REFERER
New site setting: `embed_any_origin` that will send postMessages to
wildcard origins `*` instead of the referer.

Most of the time you won't want to do this, so the setting is default to
`false`. However, there are certain situations where you want to allow
embedding to send post messages when there is no HTTP REFERER.

For example, if you created a native mobile app and you wanted to embed a list
of Discourse topics as HTML. In the code your HTML would be a
static file/string, which would not be able to send a referer. In this
case, the site setting will allow the embed to work.

From a security standpoint we currently only use `postMessage` to send
data about the size of the HTML document and scroll position, so it
should be enable if required with minimal security ramifications.
