UX: adds hover effect on lightboxed images (#8416)
* UX: adds hover effect on lightboxed images

This commits also adds two scss functions:

- is-light-color-scheme()
- is-dark-color-scheme()

This hover effect won't be added on dark color schemes, as images already standout nicely on dark backgrounds.

Sam 0c11caf796 UX: remove gray background from lighbox
This avoids a 3 way transition when loading images

- grey
- ultra low res
- full image

Instead we go

- ultra low res
- full image

Robin Ward 0e710dc573 Improvements to Lazy Loading
- Now applied to all images over 150x150px

- Stores the width and height in the WeakMap rather than using
percentages for accuracy

- When oneboxed images are hidden, they are given a subtle border for better
visibility.

- Don't apply when in the composer. Causes flickering.

Robin Ward 662cfc416b FEATURE: Show a blurry preview when lazy loading images
This generates a 10x10 PNG thumbnail for each lightboxed image.
If Image Lazy Loading is enabled (IntersectionObserver API) then
we'll load the low res version when offscreen. As the image scrolls
in we'll swap it for the high res version.

We use a WeakMap to track the old image attributes. It's much less
memory than storing them as `data-*` attributes and swapping them
back and forth all the time.

UX: increase selector specificity so that "inline" lightboxes in quotes don't get backgrounds
When a quote is not expanded and it contains lightboxes, those lightboxes are not displayed and instead we show a link that looks like this `[image_title]` 

These still have the lightbox CSS class and so they still get the backgrounds we add to lightboxes while they load. Increasing the selector specificity prevents that from happening.

Robin Ward 6797a710aa FEATURE: Lazily Load Images as they scroll into the viewport.
This feature uses the Intersection Observer API

https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API

It should be compatible with all modern browsers. Non-Edge IE is *NOT*
supported, so in that particular browser images are loaded by default.

Upgrade to FontAwesome 5 (take two) (#6673)
* Add missing icons to set

* Revert FA5 revert

 This reverts commit 42572ff

* use new SVG syntax in locales

* Noscript page changes (remove login button, center "powered by" footer text)

* Cast wider net for SVG icons in settings

- include any _icon setting for SVG registry (offers better support for plugin settings)

- let themes store multiple pipe-delimited icons in a setting

- also replaces broken onebox image icon with SVG reference in cooked post processor

* interpolate icons in locales

* Fix composer whisper icon alignment

* Add support for stacked icons

* SECURITY: enforce hostname to match discourse hostname

This ensures that the hostname rails uses for various helpers always matches
the Discourse hostname

* load SVG sprite with pre-initializers

* FIX: enable caching on SVG sprites

* PERF: use JSONP for SVG sprites so they are served from CDN

This avoids needing to deal with CORS for loading of the SVG

Note, added the svg- prefix to the filename so we can quickly tell in
dev tools what the file is

* Add missing SVG sprite JSONP script to CSP

* Upgrade to FA 5.5.0

* Add support for all FA4.7 icons

- adds complete frontend and backend for renamed FA4.7 icons

- improves performance of SvgSprite.bundle and SvgSprite.all_icons

* Fix group avatar flair preview

- adds an endpoint at /svg-sprites/search/:keyword

- adds frontend ajax call that pulls icon in avatar flair preview even when it is not in subset

* Remove FA 4.7 font files

Run `prettier --write "app/assets/stylesheets/**/*.scss" "plugins/**/*.scss"` after making sure you installed it with `yarn`
