More Minor pAI Tweaks

- EMPs will only instantly kill full health pAIs on a 20% chance,
possible brute/burn from EMPs isn't instantly deadly anymore.
- pAIs can no longer bump things around.
- Cleans up unneeded if statement in pAI pull proc, still cannot pull
anything.
- pAI card (not mobile form) now properly reacts to explosions.
- Adds 1/10 second delay between a pAI being hit/bonked and closing up
(Effectively meaningless gameplay-wise).
