Tooltip component

[paulirish]

On mac the chrome/system tooltip (that shows [title] takes like 1 second to display. (iirc, it's twice as slow as windows/linux for no good reason)

regardless, i think we want a JS tooltip component so that the values behind [title] are a lot more accessible. we hide some good stuff in there.

i found these without looking very hard

• https://react-hint.js.org/ doesn't feel right to me, personally.
• https://ajainvivek.github.io/preact-fluid/#tooltip would be nice without the animation
• https://react-tooltip.netlify.com/ i dig this style. i love the mouse tracking thing (tho i'm not 100% that we want it here.. but maybe?)
• https://codepen.io/fuggfuggfugg/pen/mqdBH what can you say. the man's got taste

Fully bike shedding, but agree that while the mouse tracking thing is cool I'm not sure we want it in the UI. I like the second one (preact-fluid) without animation. :)
