`shared.scss` double import.

Hi,

I'm not sure this is an issue, you may have your reasons to do it.

In cssgram.scss we import shared.scss but we also do it in every filter .scss.

Is there a reason to do that? The resulting CSS is double the size. If there's a reason to it, we may need a small settings.scssfile to choose filters, different variables, or even if we want to create the class or live happyly ever after only with extend.
