SCSS file management.

Problem/Motivation

A developer may want to set the path or download SCSS files that are created and stored by the editor.

User interface changes

Under settings create a form element that allows a developer to set the path so that the SCSS files can be stored where the developer wants. Or the download button to copy a zipped version of the file.

API changes

Create API functionality aligned with Drupal best practice that achieves the following goals.

1. Accept a variable string from the UI that sets the path of the development team
2. Zip file is created by the system and downloaded through the browser.
