Title: Make this plugin work with sbt subprojects

Make this plugin work with sbt subprojects, where package.json is in the subproject directory. In that case, we should explicitly pass the --prefix param to npm with the subproject's directory.

The directory structure would be like this:
```
root/
build.sbt (root)
project/
plugins.sbt (containing sbt-js-engine)
subproject/
build.sbt (subproject)
package.json (packages that subproject requires)
node_modules/ (js modules that subproject can access)
```
