Face-to-face (plugin)

Noticed a small bug:

When I book attendances for a session, I select the attended users with the checkboxes and they are saved OK. But when I click "take attendance" again, the checkboxes for the already attended students are not checked. It's a bit difficult to select the attended users when all the checkboxes are empty.

Also, the checkboxes are pretty far apart from the students' names, so it's pretty hard to see which box belongs to which student, if there's a long list of students.
