Duke3D: Return to centre improvements.

Browse source 
- Lock player horizon while returning to centre.
- Precisely scale player's horizon in time with rate at which 'pPlayer->return_to_center' decrements.
- Check player's horizon is between 99 and 101 degrees, not 99.9 and 100.1. The extra 0.9 degrees of precision is not noticeable and is dramatically slower.
- Reset 'pPlayer->return_to_center' to '0' when player's horizon is at 100.
- Match q16horizoff precision to precision of q16horiz.
