Customize the Dropdown Scrollbar with CSS

This is the only lesson in which we will fallback to CSS to give our dropdown's scrollbar a fancier look because this is very browser dependent and there is no way (yet) to do this with elm-ui.

We will target ::-webkit-scrollbar, ::-webkit-scrollbar-track, and ::-webkit-scrollerbar-thumb to get the scrollbar looking exactly how we want it.
