[rules-dev] Freeze status to fix split packages

Quick status update: - Drools-compiler has been namespaced - Drools-core has been *partially* namespaced Still todo: - drools-core (the rest) - kie-internal - kie-api There are no compile errors currently. Edson is working on getting the tests etc running again. I 'll try to finish drools-core on Sunday (if possible). *Feel free to push commits between now and Sunday morning, but make sure they compile (including downstream).* Next status update on Sunday evening. We 'll probably delay splitting kie-api and kie-internal to a later date next week.
