Replaced with piano song

- Replaced with the piano melody with an song find in typical RPGs.
- New Remove Pants/Shirt buttons
- About window was redone with the license moved to it's own dedicated window that now includes CC-BY 4.0 notice as well.
- New assets: blue camo pants and the shirt from the cancelled "What's New Zack?"
- The Zack sprite was modified to work with the new shirt. This doesn't affact older ones, though.
