Add circular cycle for navigating works.

Add jumping to the end if you go up from the first work and then jumping to the first work when you go down.

Right now you have to hit :arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down::arrow_down: to get to the bottom of the list.
