Minor graphical updates and code cleaning.

- Padded game score display, and always display 2 digits in front of the decimal (e.g. 00.00% instead of 0.00%).
- Keep map progress circle at a fixed location instead of basing it off the score length.
- Moved some track resets (pause + restart at preview) to trigger upon loading the song menu.  Fixes weird behaviors when leaving the game state.
- Cleaned up trailing whitespace and added missing overrides.
