By the way, I worked on this with less than 3 hours of sleep during HackSC, so there may be obvious errors...

Cool! I'll let someone else review, but this looks great.

Typo: VisualStyleBackgroundPicker.js

Since a lot of this code came from an existing file with a copyright, it should have both you and the original ("Copyright (C) 2014 Apple Inc. All rights reserved.")

Style: Brace on new line

Ah OK gotcha.  I wasn't really sure how to go about doing that, but what you wrote makes sense.  Thanks!

It is usually better to have a wrapper listener to make sure the function isn't confused by the first argument being an event object.
