Fix multiscene ops and batch script generation

0.6.0:

- feat: button to generate a background rendering script to batch multi-scene
- fix: exposed checkbox to change scene AA settings, should be on except if there are NG_merges. (auto-off when using merge nodes buttons)
- fix: default generated scene have native AA
- fix: adding layers from object in other scene use active scene (stop always rerouting to 'Render' scene)
