- IndividualAssignmentsTable: add View Project (new tab) as first dropdown item
- AwardShortlist: make project title a clickable link opening in new tab
- ProjectStatesTable: change View Project from same-tab Link to new-tab anchor
- Round page: Awards tab now only shown when roundAwards.length > 0
