This improvment will allow adding entries with content per user via the dataform csv import.

In the csv import form the instructor will select to add entries per participant. With this option each csv line will constitute a new entry for each user.

For example:
Given a dataform with a text field Text in a course with two participants, participant1 and participant2.

I go to the csv view and click import.
I set the field "Add entries per participant" to "Yes"
I set the field "Csv content" to
"""
Text
First entry
Second entry
"""
I click "Import"

4 entries will be added, two for participant1 and two for participant2, such that for each participant, one entry will show the text "First entry" and the other will show "Second entry".
