Subject: [PATCH] Ignore Dimension NBT field in Entity data

Minecraft is trying to set Dimension Objects based on a Dimension ID

Dimension ID's for custom worlds are dynamically allocate dand not guaranteed
consistent.

This removes checking the NBT data, as the Entity will always have its
DimensionManager set to the world it is being placed into.

This fixes corrupt entities breaking chunk saving in custom worlds.
