Add the Closure Compiler/Library/Templates dependencies

This CL does a few things:
- Adds the template Soy-to-JS compilation (note: this requires the extra
  soyutils_usegoog.js file separately so that the compiled *.soy.js files work
- Adds the Closure Compiler to compile and check our JS
- Adds an NPM task to allow us to download dependencies
- Adds the Closure library as an NPM package

Note: this probably won't compile until we fix the test JS files
