Header url reorg

Alright, since I haven't heard anything I assume it's good so here's the pull request. Refreshed the look of all the pages. Left all the old pages in html/ there but added a meta refresh and js redirect to them to point to the new equivalents. Let's do this! /cc @bclark8923 @jfarmer
