Roles

Introduce the concept of "roles".

The Role model

(not school-term-related)

• name
• short_name
• fg_color / bg_color

Changes for GroupType

• available_roles

Changes for PersonGroupThrough

• roles

Frontend changes

• Add CRUD management for roles
• Add tags with roles in group members list
• Add selection of available roles for group types
• Add role seleection when assigning members to groups (probably needs a full re-design of the group edit form; e.g. separate member management from editing)

Follow-up

• After this is introduced, ping/plan #591 (closed) and #406 .
• Evaluate how to use roles in the calendar system (participants in web UI and in iCal)

Group edit form is still legacy, so this is a good point to redo it.
