Move the admin dashboard to a subdomain (#56)

This commit moves the administration dashboard from its current
location at /dashboard, to a subdomain named dashboard. On deployed
sites, this will change the dashboard location from
www.makigas.es/dashboard to dashboard.makigas.es.

Given that the public website has no need for user authentication, the
login path has moved to the dashboard subdomain as well. Therefore,
www is only used for serving public pages now. Everything related to
the admin panel is now located at the dashboard subdomain.
