Evaluate option to share Contract code with ipfs instead of GitHub Gists

[achimcc]

In the Prototype, the sharing functionality is provided by creating Github Gists. This works, but it relies on the Server and also on GitHub servers. A more decentralised solution would be great.

• Explore options to save Contract Code on ipfs instead of in GitHub Gists.
• Can we do this from within the broswer without requiring a user login?
• Can we use https://www.textile.io/ for this? This would be the best solution, since it is already used in Contracts Explorer.
• Or other tools, possibly: https://thegraph.com/en/ ?
