ScreenSelectCourse now uses ScreenSelectMusic. This removes a

lot of duplicate code (some of which was out of date, such as the wheel
input behavior).  Themes no longer have to tweak both of these screens
individually; only the metrics for ScreenSelectMusic need to be changed,
except where they're explicitly overridden.
