Add option for precise hologram teleport

When moving holograms quickly (for example, a chat message over a player's head) lines may not be aligned correctly after moving for a while. Precise hologram teleporting prevents this issue.

Some people won't need it, and disabling it may slightly improve the performance (depending on the number of holograms).
