Attach spyglass to player model to make compatible with animation texture packs.

[jpuqt]

In most other mods accessories move with the player, such as Artifact's which make them compatible with animation texture packs. However, the spyglass isn't attached to the player in the same way as other mods. This causes the spyglass to look off when using animation texture packs or mods as they spyglass doesn't move with the body while other accessories do. Making the Spyglass render on the player the same way other mods do may fix the issue.
