No problem, thanks! There are a few linter errors, could you take a look?

@feimosi: just fix them yourself and push to @davidhellmann fork and then just squash + merge.

I can't push to other's forks without some extra permission, can I?

@XhmikosR Interesting, thanks! :)

@feimosi: I replied via email but you probably missed it.

Now regarding this PR... are you sure all supported browsers have classList support?
We should add ESLint plugin compat to automate this.

@XhmikosR I didn't get that message.
Anyway, I've added an extra check for classList support here:
https://github.com/feimosi/baguetteBox.js/pull/143/files#diff-4634650f8cf2cdceb34291a9bcf4c23fR472

I'll test test thoroughly before the next release too.

@feimosi: I wouldn't personally go with that. If you still want to support < IE 9 you should do this https://plainjs.com/javascript/attributes/adding-removing-and-testing-for-classes-9/

Sure, it works only in newer IE, but using this option won't break anything, so I don't see any hazard here. Treat it as progressive enhancement, I just need to mention that in the docs.
