Split the furious words section into two

[benlk]

The list right now is composed of two categories of words:

• words describing a situation's objective badness
• words describing how the speaker subjectively feels about a situation

Because these are two very different sort orders, it is difficult to put them in the same single list in any sensible order. And therefore, the lists should be separated.

• split list
• identify overlap words and put them in both lists
• styles for side-by-side display of lists on HUGE screens
• answer question of which goes first on smaller screens
• create fork of tufte.css in SASS/LESS.
• create branch of tufte.css adding CSS @supports (text-decoration-skip:ink) lines and PR it into tufte.css

Forking tufte.css in LESS/SASS has been done at https://github.com/sdruskat/tufte-css-jekyll, though it's included as part of a greater library. And really it's beyond the scope of this project. benlk.com uses a fork of tufte-css-jekyll now, and that should eventually be cleaned up for posting to github, maybe.

Also, text-decoration-skip:ink is now the default in modern browsers, so the thing with the shadows can be avoided.
