Electron support

Relevant ipfs issue: ipfs/js-ipfs#843

In electron we want to be able to use an internal go-ipfs node to leverage the advatages it has over js-ipfs. If we can't do that, we want to at least be able to run js-ipfs in the node process of Electron so that it can use more transports than it would in the renderer process.

Unfortunately at the moment js-ipfs only works in the renderer process so it would be the same as running from the browser.

The other way is connecting to go-ipfs using ipfs-api, we have an issue for that: #9

For running a go-ipfs inside node/electron, that's easy: it's being done in this app: https://github.com/ipfs-shipyard/station using this library: https://github.com/ipfs/js-ipfsd-ctl. I'm actually already using this in #9

So the roadblock we are hitting is that we need #9 to comfortably use ChluIPFS from electron, otherwise it's like using the browser.

@fazo96 Don't worry about using js-ipfs inside the electron based architecture.

We will use electron only if we want to use go-ipfs, otherwise we provide a chrome extension or a chrome app.
