Add template files for Node.js

Modified the aimcreate-pkg script to copy Node.js template files.
The files are:
- `TemplateModuleNode.cc`: Template for Node module wrapper
- `binding.gyp.parent`: used to configure node-gyp when building the addon
- `package.json.parent`: used to add hook to `npm install` event to build the addon
