Better TV support, icons, activity_main refactoring

- on Android TV you'll be able to navigate with D-pad in main fragment and in the player. But not between them for now
- play/pause/next/previous buttons are smaller now
- replaced ic_list with previous version of it
- activity_main looks better which helps with Android TV support
