Speedhack protect tune

This updates the calculations in the speedhack protection code to more appropriate values now that the USER_RUNNING_SPEED had been increased lately and matches the real player movement speeds.
This also does the calculations in a better scale.

IMPORTANT:
piMoveStepTolerance has now another scale and the default value in settings.kod was adjusted

After this goes live piMoveStepTolerance in the existing settings instance MUST be adjusted: set obj 1 piMoveStepTolerance INT 144
At least to 144, likely higher (guess up to 256) depends on player complaints...
