Organisations with seats and shared tokens

Teams can now work under an organisation instead of personal accounts.

• Invite members by e-mail and give them a role: owner, admin, member or billing manager.
• The Team plan is billed per seat; billing managers take no seat.
• Organisation tokens give CI and servers access without tying them to a person.
• An audit log records who changed what, and a data processing agreement is available to accept online.
