Add option to set primary group if no current primary group

[jcoates (Joseph Coates)]

I am going off of @trash’s explanation… I’ve shied away from using this feature because of the potential problems it could cause.

What exactly does "Automatically set as primary group" do?

Yes If you have more than one primary groups (for example groups A and B) and a user of A enter in the group B, the last group (B) will be automatically set as primary. Admins can change the primary group for each user I don’t know about titles but in my memory some configurations of the group remain even if a user leave the group (e.g. if you set the group to assign TL4, when a user leave the group he still remain to TL4).
