Clean up nitrogen lung quirk code

- Change code to store type of old lungs, not instance
- Delete old lungs instead of trying to move them to nullspace, fixes runtime
- Fix hardcoded nitrogen lungs path in mutantlungs setting
- Use the right proc to attach the dogtag to the uniform
- Fix dogtag not setting examine text properly
- Fix override of attach_accessory that was missing args
