Make module production ready

[ihor-sviziev]

For production purpose we need to have good working module.

This PR doing following changes:

1. Hides toolbar (pagination was hidden in Fix selector for pagination #30, but limit appeared back, it's not needed when infinite scroll is enabled)
2. Removing "Congratulations, you've reached the end of the internet." text. On real production website it's better just not to add anything

Thanks.

1. This makes sense, we'll merge together with Fix selector for pagination #30
2. Most of our customers do actually seem to use that feature. By providing a default message we make sure our users know about the feature, and they can always choose to customized it with a few clicks. Could you extract it from the commit?
