Title: create a relationsChanged signal for relation manager

I had the problem of being able to when the relations change within a project.
I am not sure it is the best place to do it though.
What do you think?

(I also renamed the argument of QgsRelationManager::removeRelation fron name to id, since it's removed by id)
