* Fixes an issue where long translations cause layout issues
* Fixes an issue where the alignment shifts when switching between signup/login
* Makes some of the margin/padding more consistent
* Removes duplicate .login-modal and .create-account classes and replaces them with .login-modal-body and .create-account-body
* Adds another color transformation so we could remove prefers-color-scheme... the problem with that was that my OS' UI might be set to something different than my Discourse preferences (prefers-color-scheme only responds to OS UI settings)
Using arrow functions changes `this` context, which is undesired in tests, e.g. it makes it impossible to setup things like pretender (`this.server`) in `beforeEach` hooks.
Ember guides always use classic functions in examples (e.g. https://guides.emberjs.com/release/testing/test-types/), and that's what it uses in its own test suite, as do various addons and ember apps.
It was also already used in Discourse where `this` was required. Moving forward, it will be needed in more places as we migrate toward ember-cli.
(I might later add a custom rule to eslint-discourse-ember to enforce this)
This gets us closer to how newer Ember versions want to do things, but
with a bit of Discourse flair.
`acceptance` now takes a function as a parameter, and tests need to be
declared in that new function context.
A new helper, `needs`, is passed as a parameter. You can use it to set
up the test the way you want.
We used many global functions to handle tests when they should be
imported like other libraries in our application. This also gets us
closer to the way Ember CLI prefers our tests to be laid out.
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
