New scss files

These are placeholders for now until they are populated with real

Adding sass compilation

We compile sass using grunt-sass. Running `grunt watch` will
automatically compile our sass, as long as we properly use our
screen.scss (which should import all of our styles ever)
Proper setup of frontend development environment

1. Compile our sass and put it in the compiled/css directory.
2. jshint and copy our js into the compiled/js directory
Reconfiguring this to properly handle the new configuration
