This PR merges webtorrent-tracker into this repo. Keeping the code in
sync between the two repos was becoming burdensome. This change should
not effect performance of the server since the webtorrent tracker is
disabled by default.
To enable the webtorrent tracker (disabled by default), do:
```js
var server = new Server({ ws: true })
```
