Update to new SASS version?

[macroecolab]

Great template, thanks for making it open for public use. When I tried to use it with Jekyll and Bundle via bundle exec jekyll serve, I get a bunch of warnings about deprecating Sass code. The links are below.

Any plans to update the .scss files to avoid breaking in the future? I don't have enough expertise to do it myself, and I had trouble using the Sass migrator tool.

Thanks very much,

Jamie
