Handle CraftPlayer#setSpectatorTarget better
Use a proper teleport for teleporting to entities in different
worlds.

Validate that the target entity is valid and deny spectate
requests from frozen players.

Also, make sure the entity is spawned to the client before
sending the camera packet. If the entity isn't spawned clientside
when it receives the camera packet, then the client will not
spectate the target entity.
