* add a system_font_ui setting on the server

* Plug the system_font_ui on the front-end

* add EN/FR locales for the new setting

* put Roboto after all other fonts

* remove trailing whitespace so CodeClimate is happy

* fix user_spec.rb

* correctly write user_spect this time

* slightly better way of adding the classes

* add comments to the system-font stack for clarification

* use .system-font for the class instead

* don't use multiple lines for comments

* remove trailing whitespace

* use the classnames module for consistency

* use `mastodon-font-sans-serif` instead of Roboto directly

* Update links in status content on update as well as mount
Fixes occasional bugs with mentions and hashtags not being set to open in a new column like they should, and instead opening in a new page

* use classList instead of raw className

This fixes a warning on status unmounting (e.g. deletion).

This also resets IntersectionObserverWrapper on disconnect to avoid `unobserve()` calls
which has bug in Edge.

* Small adjustments

About the report part.

* Update time format

* Fix embedded SVG fill attribute

SCSS darken/lighten functions may not return a color value, but a color
name like "white".  See following example:

https://www.sassmeister.com/gist/c41da93b87d536890ddf30a1f42e7816

This patch will normalize $color argument to FFFFFF style.

I also changed the function name from "url-friendly-colour" to
"hex-color", Because...

1. The name "url-friendly" is not meaningful enough to describe what it
   does.

2. It is familier to me using "color" rather than "colour"
