Subject: [PATCH] Compile and load .scss directly with libsass (#76)

Even though an scss file is present, it needs to be converted manually and only the
CSS file is parsed. This pull request sets out to fix that.

there is preliminary scss support using libsass now (libsass is technically "deprecated" but there seems to be no other
c/c++ library for converting scss to css)
