[lime-dev] https on dev.libre-mesh.org

I noticed that the subdomain dev.libre-mesh.org runs with a self-signed certificate, which is annoying because casual people browsing (and security paranoid) won't accept to add an exception in order to read more and will leave... A free browser-accepted certificate can be obtained from StartSSL [1] (for that specific domain, wildcards and extended verification certs are not for free of course, but we there is no need for them).
