Allow participants to download a copy of the consent form or debrief (not all participants are capable of taking screenshots - current workaround is to email them consent form, taken in PDF from Gorilla - but if we can't collect emails, then we can't do this for those participants).

This may be useful for all of questionnaire builder (ie to let participants download a copy of their response, including a PDF) but the specific use case is for consent forms/participant information sheets and debrief forms.

Alternative would be to have a box to have Gorilla email it to participants rather than download, potentially.
