uglify upgrade breaks compatibility with older versions of node

[es128]

66f6f94#package.json should probably have been associated with at least a minor version bump.

Also, your package.json advertises compatibility with "node": ">=0.4.7". That should probably be changed.

See brunch/brunch#606.

I think it's too late to do anything helpful for the aforementioned issue, but just wanted to ensure you were aware.

We should probably move the uglify library into an optional dependency so we can maintain the node support for older versions.

The uglify dependency has been moved to an optionalDependency. This should hopefully resolve the issue on older versions of node.
