Use  js-ipfs instead of js-ipfsd-ctl

Due to some issue with packaging the [js-ipfs](https://github.com/ipfs/js-ipfs) in electron https://github.com/ipfs/js-ipfs/issues/843, I got this project off the ground with the package that adds node bindings to the go-ipfs implementation ([js-ipfsd-ctl](https://github.com/ipfs/js-ipfsd-ctl)).

This _should_ only use the [js-ipfs](https://github.com/ipfs/js-ipfs) package.
