Provide process.version to webui and component extensions

It was erroring with:

```
_stream_writable.js
var asyncWrite = !process.browser && ['v0.10', 'v0.9.'].indexOf(process.version.slice(0, 5)) > -1 ? setImmediate :
```

because our webpack config sets process to false and the process object
we provide doesn't have a version property until now.

processNextTick;
