Spacing first try
Refactor sass to not compile duplicated css
enhc typography spacing and css fixing

Basic idea of spacing for typography.

I found that I was importing completely incorrectly in sass (even
though importing works in this way in most programming langauges). I
should only import each file once unless its vars in mixins, otherwise
it will show up multiple times in the output. This means mixins all
have to be in one file.
