Republish Documentation

[decherneyge]

Looks like the docs on http://www.chartjs.org/docs are out of date to the ones in the docs folder.
For example, I did not see mention of the tooltip.itemSort in the published docs but it is in the docs source

Good call! @nnnick can you redeploy?

[simonbrunel]

I wondering if we couldn't make it part of the CI process and have it automatically deployed when creating a new tag (see #2555)?

The docs at http://www.chartjs.org/docs/ are missing the bubble charts as well.

Docs have been updated since this was opened.
