Super Mario World [Ripping All Levels]

[Barack Obama]

Revised:
- Yoshi's House Tileset: Added the correct yellow foreground palette
- Switch Palace / Bonus Game Tileset: Added the correct yellow foreground palette
- Castle / Fortress Tileset: Added the correct yellow foreground palette, changed a bit text for the curtain suspension
- Forest Tileset: Added the correct yellow foreground palette
- Ghost House / Sunken Ghost Ship Tileset: Added the correct yellow foreground palette, changed ripper tag and placed some tiles differently (assembled 16x16 tiles with two palettes)
- Athletic Tileset: Added the correct yellow foreground palette and reworked the entire sheet layout, also added more guardrails, the assembled ropes, etc.

Turns out the yellow foreground palette ALWAYS cycles through 4 different types of yellow. Even if the Yoshi coin and the curtain suspension are not even on the screen, the palette ALWAYS changes its 4th colour. Luckily, nothing else in the game except these two fg objects use the 4th colour of this palette so everything should be alright.

I've already updated all tilesets except underwater/underground, which needs an update anyway.
