style: use npm less to generate kallithea stylesheet style.css from style.less This is a minimal change to introduce less as framework to generate our stylesheet. The input less file is currently the same as the original css stylesheet, so that the delta between the input style.less and the output style.css is zero. To regenerate style.css from style.less, run: npm --prefix kallithea/public/less install npm --prefix kallithea/public/less run less These changes are based on work by Dominik Ruf.
