minimal verification that tag stats are being displayed
just display standard date for now
display a modal while waiting for the search

no spinner or styling yet
hard-coded modal window with spin.js and q keybinding to quit
move hardcoded spinner to stylesheets and cljs
fix spinner, other tweaks
make spinner bigger
remove unused goog dialog
fix timestamp formatting breaking on nulls
add spinner between screen transitions

Hopefully this improves UX on mobile + heroku and doesn't induce seizures
locally.
fix script to include index.html changes
add externs for spin.js

and workaround annoying console.groupCollapsed bug
remove unused overlay message
style tweaks
actually spin off correctly - how it was working before?
move rendering nses to under rendering/
a less brittle externs file
