Format <head> correctly

See original GitHub issue

This mostly means generating a ton of icons, and being smart about it. But from the looks of it we can do this from 3 required resources:

icon-512x512.png for manifest.json
safari-icon.svg for safari-pinned-tab (needs to be black/white square, see this tutorial)
a twitter / fb card in .png with dimensions of1500x1120

In addition we’ll need the following values:

title - used to describe the page in the browser’s tabs
description - used to describe what the page is, in long form; used by search engines and the like. Can be derived from manifest.json
themeColor - used to change the color of the header on mobile. Can be derived from manifest.json
twitterName - name of the organization on twitter. Useful for shares.
mainUrl - the homepage for the site

Ohh, another cool one is <link> dns-prefetching; allows warming up the cache for external requests. String matching on a JS bundle should get us a longgg wayyyy C:
