Some graphical improvements and fixes.

Browse Source 
- The music position bar in the main menu is now clickable (changes track position).
- Fixed scroll bar height function, and merged all scroll bar drawing into a single Utils.drawScrollbar() method.
- Fixed the buggy song menu scroll bar.
- Scaled the sizes/positions of the main menu music icons (previously fixed/hardcoded).
