Feed: Mention teams or groups of users

[Innders]

Story

A director is making a comment on a sequence and wants all the lighters to know it's a dark scene.

Problems

• You don't need to know the specific roles of all users.
• You don't need to add potentially 100 mentions on a comment.

Proposal

• Teams can be mentioned just like users using the @ notation.
• Every user in that team gets notified.
• Hover over a team to see it's leader and number of members.
• Click on a team to open a dialog showing the full team.

TODO

• [ ] BE suggestions API support.
• [ ] Is the type user or a new team type?
• [ ] Suggestions for teams shows groups icon - team name - no. members
• [ ] Hovering team tooltip
• [ ] Clicking team dialog.
