For a rear arc turret, lockCameraTo only works in half of the turret arc.

The half-arc that works changes based on whether the limits are positive or negative angles
```
initTurn = 180;
minTurn = 90;
maxTurn = 270;
vs
initTurn = -180;
minTurn = -270;
maxTurn = -90;
```
Current use case is to allow player to have AI gunners track their view direction, this issue limiting rear ramp gunners.
