Server metrics on multi-axis graphs.
The new dashboard javascript is checked out in git, static/new-dashboard.js,
so it works out of the box with just the webserver set up.
To develop it:
cabal install purescript-0.6.8 # or later
pacman -S npm
npm install pulp
cd new-dashboard
pulp dep install
# try
pulp build
pulp run
# deploy
pulp browserify --to ../static/new-dashboard.js
