Move the docs / website / blog to Gatsby and Post-MVP TODO

Moving the site

@syrusakbary and I agreed to get the docs out sooner rather than later, but we want to move all of the online Wasmer Resources under a single domain and repo on Gatsby 😄

Post MVP TODO

• Only show parts of the example?
• Add a way to include files from markdown to be able to show their source code.
• Add the Wasmer Logo to the header, and change header color? Actually, with the move, just re-use the same header component

Also, be sure to also try and do some feedback items from #6 when we do this move

We don’t need this any longer :)
