iPod 4th Gen Clickwheel

Clickwheel and center button for a 4th generation iPod. Will not fit other models. Center button is currently untested as I don't want to disassemble my clickwheel more than necessary.

Clickwheel disassembly: see [this video](https://www.youtube.com/watch?v=bu4HUVjWnUE&t=208s) starting at 3:28. Be very careful not to stress the center button's ribbon cable during the removal.
