world.jar: never come back

Notes

• Finding a note shows a "Note found" pop-up that tells you which key opens your notebook.
• The note sound comes a moment after the chest opens, so the chest doesn't drown it out.
• It's also no longer the same sound as the one that leads you to note chests, so you can tell them apart.
• Notes are written in a new handwriting.
• Notes are much easier to read: the blurry shadow under the text is gone, and the ink is darker.
