demandimport: store level argument on _demandmod instances The 'level' argument to __import__ was added in Python 2.6, and is specified for either relative or absolute imports. The fix introduced in e160f2312815 allowed such imports to proceed without failure, but effectively disabled demandimport for them. This is particularly unfortunate in Python 3.x, where *all* imports are either relative or absolute. The solution introduced here is to store the level argument on the demandimport instance, and propagate it to _origimport() when its value isn't None. Please note that this patch hasn't been tested in Python 3.x, and thus may not be complete. I'm worried about how sub-imports are handled; I don't know what they are, or whether the level argument should be modified for them. I've added 'TODO' notes to these cases; hopefully, someone more knowledgable of these issues will deal with them.

revert: use opts.get If you want to programatically perform a revert right now you need to include a date=False parameter due to the use of opt["date"] instead of opt.get("date").
