Follow links on disk when uploading node_modules

[pulkitsinghal]

I use several nodejs submodules that are under active development as the dependencies for my iron worker.

node_modules
│   ├── request
│   ├── my-mod -> ../../../../.nvm/v0.10.33/lib/node_modules/my-mod
│   └── xmlreader

I accomplish active development by using the npm link command instead of npm install for putting some of the dependencies under the node_modules folder. But I noticed that specifying dir 'node_modules' does not upload any of the sub-directories under node_modules that happen to be sym/soft linked by the npm link command.

Please add the ability to tell the iron worker upload process to follow and upload links in the filesystem too.
