Major song menu improvements and fixes.

Browse Source 
- Song group nodes are now hidden when the group is expanded.
- Setting a new focus will always move the focus into view.
- Left and right arrow keys now shift focus by exactly 1 node.
- Render the version string for unexpanded song group nodes containing only 1 beatmap.
