Allow sub-theme to import a module's Sass files

So I discovered I nice configuration gem for our STARTERKIT's config.rb file.

From http://compass-style.org/help/tutorials/configuration-reference/

add_import_path

Call this function to add a path to the list of sass import paths for your compass project. E.g.: add_import_path "/Users/chris/work/shared_sass"

With that we can import any module's Sass mixins, variables and functions into our sub-themes.

Here's a quick gist of my idea: https://gist.github.com/2378131
