Merge: from autoturret_optim
- Bugfix for turret not reacting to player in front when powering up (caused by me)
- Bugfix for turret not identifying new target if it snuck from behind then walked in front (likely me as well)
Tests: standing in front, sneak in from behind then to front, sneak damage, flying from far, depower-power turret - turret finds a target & shoots
