I believe you meant to write `npm run test:node` in the instructions on how to run the unit tests. The `npm run test:node:core` line was written twice. Cheers

#1456)

This reverts commit 48aceb1.

This issue was fixed upstream in git-validate with the release of
version 2.2.4. AEgir 15.0.1 uses that fixed release. As we use
version ranges for dependencies, it is automatically fixed now.
Hence reverting the original commit.

Also updates pinning to support CIDv1

`init` and `start` both emit any error they encounter. `boot` will then receive that error and also emit it! This PR adds an `emitted` property in `boot` to errors that came from `init` or `start` so that later in the code it knows whether to emit it or not!

refs #1459

This PR adds a new config property `preload`:

```js
new IPFS({
  preload: {
    enabled: false,
    addresses: ['/multiaddr/api/address']
  }
})
```

* `preload.enabled` (default `false`) enables/disabled preloading - **should the default be false?**
* `preload.addresses` array of node API addresses to preload content on. This are the addresses we make a `/api/v0/refs?arg=QmHash` request to, to initiate the preload

**This PR upgrades the following APIs to preload content**. After adding content with `ipfs.files.add` (for example), we make a request to the first preload gateway addresses (providing `preload.enabled` is true), and will fall back to the second etc.

* [x] `dag.put`
* [x] `block.put`
* [x] `object.new`
* [x] `object.put`
* [x] `object.patch.*`
* [x] `mfs.*`

MFS preloading is slightly different - we periodically submit your MFS root to the preload nodes when it changes.

NOTE: this PR adds an option to `dag`, `block` and `object` APIs allowing users to opt out of preloading by specifying `preload: false` in their options object.

When JS IPFS requests content not stored locally it needs to ask the peers it knows about to provide it if they have it. The peers are not relays so if they don't have it, they won't find it and provide it to JS IPFS. However, if we issue a preload request prior to these requests we prompt the preload nodes to fetch the content using their DHT and they can then provide it to JS IPFS.
