Remove old website files.
Add new index page with redirect.
Remove Rakefile that built the old website.
Clean up spacing in index.html
More robust index page for server root.

- Only redirect when this page is being served up on one of our
  domains.
- Show a nice page that explains what is happening with a link to the
  home page for users who run the Ruby server.
- Note: This doesn't matter in the node use case since many node users
  will use the `vwf` command line tool.
