Alt warnings in production mode

Hi, I use alt with react and webpack's uglifyjs plugin. After creating minified version of browserified js bundle, alt prints warnings in chrome's console:

```
ReferenceError: A store named e already exists, double check your store names or pass in your own custom identifier for each store(…)
```

Is it possible to not show warnings/errors when `NODE_ENV` is set to production, just like React has it now?

Many thanks.
