SCI32: Fix save patching for ScummVM dialog

- Patch game super object for saving instead of game object
- Remove re-adding planes+screen items, game::replay does that
We would only have to do that for soft-failing on restore
- Change debug levels of kNumLoops/kNumCels to 9
- Add special comment about -info- selector in syncWithScripts()

This should now make ScummVM menu saving work properly at
least in SQ6.
