Super Mario World [Ripping All Levels]

[Barack Obama]

Revised the following sheets, mostly for unifying the sheets and icons:

- Yoshi's Island 1-4
- #1 Iggy's Castle

As before, the original rippers are credited due to their time consumption to create these sheets. I also added a clean rip of Yoshi's House without sprites blocking the view and the bg colour sharing the same palette as the tiles. The props from this sheet (birds, smoke, etc.) are still on the site, but in another section.
