New function: create team/taskforce

[akrobatim]

Within a circle, be it a community, a project or an event etc, it would be neat to create a team or a taskforce. This would be a group of people gathering around a specific target or goal (like the Connectathon). The team would have their own team space with a kanban and a team chat along with a task manager. Team members could be displayed at interwoven hexagon tiles, making use of the hexagonal shape of individuals.
