Update team page
Update hifis.net/team.
- Added communication experts
- Renamed "Team" to "Coordinators, Managers", because the overall team is bigger!
- Simplified "rank": 0 (not displayed), 1 (Coordinator/Manager), 2 (Comm Officers). Open for extension
- Remove some members that are not longer here
