Merge #399

399: Prepare ipfs release r=koivunej a=koivunej

This PR updates Cargo.toml, so that I can release it.

I hope adding the `version` for the `path` deps does the trick, at least `cargo publish --dry-run` seems to produce an ok crate, with:

```
[dependencies.ipfs-bitswap]
version = "0.1"

[dependencies.ipfs-unixfs]
version = "0.2"
```

The crate ends up containing the Cargo.lock file which I am not so sure if it should be excluded?
