Attaching Spyglasses to helmets.

Spyglasses on their own don't seem very useful and will likely just annoyingly makeup inventory space. This is just a use that will allow for more player convenience where you can attach them to helmets using a smithing table. Upon wearing a helmet with a spyglass attatched to it you can simply use the ctrl key at any time to zoom in with it similar to how optifine works but the same spyglass point of view.
