corrected yasnippet startup
Finish feature-replace-yasnippet-bundle
replaced yasnippet-bundle with yasnippet
fix bug installing yasnippet over yasnippet-bundle

  yasnippet-bundle has not been deleted.  Better to add two lines to
  starter-kit.org than have every user run into this problem on their
  next update.
