AlertDialog owns its view, which causes problems with TabLayout on API 21 and 22. Now using AppCompatDialog instead so that we can own the view ourselves. Also: - Renamed layout files from download_xyz to track_selection_xyz. - Added OK and Cancel buttons to the view. - Applied alert dialog style to the "normal" dialog to get a nicer UI.
