Adds a new docs website, built with Gatsby JS, to replace the old Jekyll site. Source code for the new site lives in /www (although markdown and YML data still comes from the legacy /docs folder).
Changes to either markdown or website source code can be previewed on Netlify. The react-js bot should automatically add comments to each PR with preview links. (This preview is generated by running the newly-added yarn build:docs command in the root package.json.)
The majority of the changes in this PR are contained within the new /www directory. However some minor modifications have been made to existing content in the /docs directory:
* Modified frontmatter author block to always be an array
* Small markdown formatting tweaks
* "Write Code in Your Editor": Split step 5 into 2 steps
To me it wasn't clear (enough) that I had to copy the file's content from [here](https://codepen.io/gaearon/pen/oWWQNa?editors=0010) *and* add the three lines to the top.
* Update tutorial.md
The tutorial hints that a change can be made that allows you to go back
in time then click in the board to create a new entry, but the change is
already present in the example code.
This fix removes the hint and re-words the explanation of the change the
example code is making.

Is it possible to be more clear here?
This implies that we are removing the constructor from GAME, and not board (which is what I believe the author is trying to say).
It took me several reads to understand.
With this edit, it is now clear that the adjustment is being made to -Board- and not to -Game-
* also remove "for Board earlier"
* Remove spread operator
I believe what was meant here was to express that you would create the new player object with all the previous properties of the existing player object in addition to now updating the score value. That being said, this is a simple example, and the player object clearly has no other values. Objects are not (by default) iterable using this operator, so this little piece does more harm than good. I believe the new example to be much clearer.
* Using Object.assign()
* Tweak wording
The tutorial wants to throw a 'warning' and explains about 'key' of React's list, but it throws nothing since there is sensible key.
"key={move}" should be removed, and added after explaining about key.
