Spec links should not be inline but should be referenced at the bottom of each page #86

I think if we're trying to attract designers, we shouldn't have links to W3C specs in the paragraphs of project pages. They are distracting and off putting for this audience. Instead, we should have them in a tablular-like format at the bottom of the page similar to how it's done on WPD

e.g. http://docs.webplatform.org/wiki/css/properties/background-blend-mode

Note: @betravis is considering including the browser support at the bottom of each page also similar to WPD, so these could be rolled out together.
