Fix relative/absolute URLs

[meiqimichelle]

• baseurl == url in config at the moment
• this should probably be relative links, but I couldn't figure out how to make this work with gh-pages and DNS settings

38 should take care of this.

Jekyll won't let us include template variables in the SASS directory, but by moving the definitions of $site-baseurl into style.css before @import "custom", we are able to set it equal to the Jekyll variable:

$site-baseurl: {{ site.baseurl }};

@import "custom"

Now that variable is dependent on the config variable set at build-time and will be correct for local and production environments.

Fixed in #38
