errorHandler logs an Error on non 404 errors
adding HTTPS support

server.coffee:
 - using americano._new instead of americano.start
 to get an app object and start the server with
 node's https module, as recommanded in Express documentation
 http://expressjs.com/4x/api.html#app.listen
 doing so make americano 'beforeStart' and'afterStart' unusable

index.glob:
 - redirecting to always use https

upload:
 - using the protocol passed in config file for pictures:
 currently http as the subdomain doesn't implement ssl
