This is a PR for #383
I do like /docs/insight as a better path then /insight.html but this is just keeping it consistent with the rest of the pages.
Cleaning up the index.md to line up with the other pages and updating…
… the inline docs to point to the correct link
Ok. I'll make a redirect page for the old link.
add redirect page for insight. ref #18 and yeoman/yeoman#415
