Significant improvements on the proctoring display UI to help the review process of proctored artifacts:
- user can flag artifacts as OK or to be reviewed
- user can add and delete comments on the single artifacts
- user can filter artifacts by "verified/not verified" "flagged/not flagged" and "all". A counter is displayed showing how many over the total number are being displayed
- interface will update as before when new pictures come in from an ongoing exam
- interface has been designed "mobile first" and with minimal, mostly graphical dependencies, to Bootstrap
