Bug 1231956: Add devtools to .eslintignore. r?pbro Devtools has a lot of eslint failures right now that would block us from turning on compile time eslint checks in bug 1229588. For now I'd like to just ignore the directory and then you can work to clean up the warnings and re-enable checks at whatever pace you like.
