Hide raw motion text

Hides the raw motion text and provides a 'raw division' notice. On unfolding the text there is a notice about the text and a prompt to summarise it.

1. "Raw Division" might not be the best title. I think we could do something effective with this title to let people know that it is unedited, and could be more useful *hint* *hint*. Relates to #584 
2. This will need accessibility and progressive enhancement improvements. I wanted to get something to see first.
