Reduce Entity Tracking Ranges

This will make players not track entities as far as they usually do.
This has multiple benefits:

1) Less bandwidth. Not sending update packets for entities that are not even close to a player, and in many cases, not even visible.
2) Less lag by maps in item frames - Default range is 160 blocks... Many players can track that item frame and cause lag and not even see it.
3) Less client lag - Not trying to render distant item frames and paintings and entities will reduce entity count on the client, which is major for shop/town worlds which may use tons of item frames.
