Broken with window.ipfs

[lidel]

When IPFS Companion is enabled in Firefox, the website breaks:

Dropping quick notes:

• missing files.get (guess: a mismatch between HTTP client in Companion and old one in the app)
• multiaddr2URL conversion produces broken URL (guess: needs updating https://github.com/multiformats/js-multiaddr-to-uri)
