Kill trailing whitespace
Use latest main.js from quick-start so window doesn't immediately close
Add Grunt tasks for building and running application
Add package step to build binary distributable; src/ -> app/ for consistency with embedded naming convention
Install in current directory instead of creating a new one

This allows us to automatically install dependencies, it won't litter
the parent directory if something goes wrong during install, and it
also makes it really easy to just re-run the generator from within
the application to get updates when new generator versions are
released.
