Fix issue with DOMTokenList

[arv]

The build.json file did not include DOMTokenList leading to
classList being brokon in 0.3.0

This adds a test that ensures that the list of files is in sync so
that these kind of errors do not happen again.

Fixes #445

This is a pretty severe bug. It caused 0.3.0 to not work when using the compiled platform.js.

Thx Arv, we'll prioritize doing another release.

Sad we didn't catch this in release testing :(

LGTM

This caused build failures:

@morethanreal Is the build.json file accessible by the bots?

Karma won't serve it automatically
