Update pagination with a simpler setup

I noticed WooCommerce's pagination system was nice and simple, and it also corresponds to what's on the Codex for paginate_links(): http://codex.wordpress.org/Function_Reference/paginate_links

I did not include the rendered CSS (library/style.css), because whatever version of Sass CodeKit is using wanted to change every line, putting braces on the same line as the last declaration, etc.
