og_user_roles 6.x-4.0

Major rewrite - removing all bonus features.

See #441776: Complete rewrite into 6.x-4.x, moving all bonus features away.

DO NOT UPGRADE from earlier versions or you will lose all configuration settings and data for additional BONUS FEATURES that were provided by this module in earlier versions.

OG User Roles 4.x only provides the base functionality (see project page). Nothing else.
