Please update to Uglify JS version 2.x

[LeoIannacone]

Hi,

we packaged your module in Debian.. However we cannot have different version of UglifyJS in our repository. The UglifyJS we ship is updated to the branch 2.x, which makes your module incompatible with.

Can you please consider an update to support only UglifyJS 2.x?

Here a patch I started to work on, can you review it ?
