add d3 and http://bl.ocks.org/NPashaP/9796212 - this is a work in progress
plug.ex: fix unused warning
Do not index pages unless they have a "public" tag
Link to a graphite container and add a timing metric
Update deps and add a statsd client
blog_content_test.exs: sync with earmark changes
Disable index page sitemap thing for now - the js is a bit hairy and I need more time to process
