- allows calling .shade files to avoid repeated `TestCommand()` calls
nit in _node-install.shade:
- name `default nodeDir` variable to match other shade files; reusing value
- #144
- problems seem primarily to occur when `node` is globally installed but a
package (`grunt` or `bower`) is not; `npm install X` fails in this case
- create the `--prefix` directory first to avoid these installation failures
- change _node-install.shade to avoid confusion when directory exists
