Error belonging to more than one group

[Jeremy Hopkins]

If a student belongs to more than one group they see the following error message:

You belong to more than one group, this is currently not supported

It would be good to make this more meaningful, however I cannot find the lang string for this.

Can you tell me which lang string this is, or if it is hard coded make it a lang string?

You’re right, it’s not a language string.

Use language strings for group membership errors. Fixes #38
