- Fix the last two Ob reference counting bugs:
  - Don't de-reference the object when duplicating it (not sure why this was left there). This fixes all the "misbehaving object: Event" messages in the console and fixes those regressions.
  - Don't reference the object when doing a lookup (not sure why this was there either). This made it impossible to kill named objects, since ObpDeleteNameCheck did a lookup before killing them, and the lookup ended up adding a reference.
- Cm still needs fixing!
