Optimize Small Entity Movement

Quellcode durchsuchen 
Optimizes small movements by entities by merging the movement
into the entities next larger movement, until enough movement
velocity has been hit.

This reduces collision detection and able to reduce movement
cpu cost by 5-7%.

The default option of 0.75 seems to provide all the gains without
any noticable behavior change to entity movement.

We have to exclude slimes due to weird jumping animation bugs.
