GH Org MIgration

All, just a quick note that we have migrated the Bokeh repo to the "Bokeh" organization on GitHub. The new URL is:

  https://github.com/bokeh/bokeh

By and large this should be a transparent and painless thing, although if you plan on submitting any Pull Requests you may need to re-clone or update your remotes. For anyone wanting full details, you can consult the GitHub docs at : https://help.github.com/articles/transferring-a-repository/

Let us know if you have any questions,

Bryan
