Convert the multimedia player and slideshow viewer into separate classes/widgets for lumina-fm, and add the new UI for the directory browser as well (no .h/.cpp source files filled out yet for it yet though).

These new widgets/classes are tied into the build for compilation purposes, but they are not actually used in the app yet.
