[XF2] Login As User [LAU2] 1.1.0

Administrators can log in as User X with this add-on. Login via the admin bar or via the member profile. Of course, this is only possible with the correct permission.

This helps e.g. to better understand problems a user has in order to be able to help him.
A link in the admin bar will allow them to quickly return to their own account at any time.
