[Feature Request] Auto-reload when dump.html is changed or dumped

Any plans to provide auto-reload the dump.html file so the developer can immediately see the `dump()` calls without hitting F5?

This should be easily done by serving the dump.html file with browsersync:
```browser-sync start --server --files "./dump.html" --index dump.html```
But the html dumped does not have body tag and browsersync requires a body tag to embed its script.
