No .scss styling for CMS

[Talha-Rizwan]

There is no sass/partials/cms/theme/ directory with .scss files for overriding styling for studio in the /cms/static/ directory unlike LMS

Even if you add the overriding *.scss files for CMS manually in the sass/partial/cms/theme/ directory, they are ignored as once in LMS. The LMS issue got resolved #24 but the CMS issue still persists.

For now overriding styling for CMS is not as convenient as LMS. By resolving this issue, developers will be able to style CMS as they do LMS.
