Title: Update EntityLiving.java

This code rework should really pair down the number of collision calls in areas overpopulated with mobs, but not effect behavior at all during typical game play any more than the other version. Please forgive any syntax errors, I don't have a compiler to test it with set up yet, but I believe you will be surprised at the improvement.
