Using object editor and URL /objectadd/ does not lead to the same result

The ObjectAddAction (used with /objectadd/ URLs) and the xactions addObject (used for example in the standard Object Editor) are creating different kind of revisions:

• always minor revisions for the ObjectAddAction
• always major revisions for the xactions

I'm not sure it's now possible to align the revisions kind because of backward compatibility issues, but at least we should be able to decide the kind of revision to create in ObjectAddAction, which is not possible right now since it's hardcoded.
