Title: Upgrading modular vars for zero output

This will change the current behavior so that setting `$include-html-classes: false;` and `$include-print-styles: false;` will produce an empty css file.

This way users can add in only the pieces they want to include by setting: `$include-html-classes: false;` and `$include-html-XYZ-classes: true;`
