"module" entry point missing in v3.0.1

[insin]

The "module" entry point added in this PR isn't present in the latest release's package.json, so Webpack 2 won't be able to tree shake by default.

It looks like it was was lost in this commit: a3dccec. I don't see a reason for its removal.

On a similar note, this also does not exist in the v4 package.json.

@timdorr Do you know why this was removed in v3?

As for v4, I haven't really looked into tree-shaking in webpack v2 yet. Looks like all we need to do is compile a version of our code that leaves all our import statements intact?

Must have been a bad merge of master back into next. I'll add it back and push a 3.0.2 to get it out there.
