ModerationObject always created even for default APPROVED

[absoludity]

The current implementation always creates a moderation object when an instance of the registered class is created. This makes perfect sense when items will be pending moderation by default. But if the policy is to display items by default and only moderate an object if it is flagged, then it would make sense in this case to create a moderation object only if/when an item is flagged (or if the automoderation is positive).

Would it be possible to have a general policy of create moderation object only if an item is moderated (ie. default or autoapproval status is not APPROVED).

I'd be happy to provide a patch if you think it's worthwhile - let me know your thoughts.
