Move groupPath from ajxp_users to ajxp_user_rights

With this commit conf.sql doesn't depend anymore on auth.sql
(auth now depends on conf for group_path filtering)
In ajxp_user_rights it's stored like:
(login, "ajxp.group_path", groupPath)

see plugins/conf.sql/update_group_path.sql for the sql migration
