kibana3-es14-connection-fail-error

Kibana 3 against ElasticSearch 1.4 throws an **Connection Failed** screen. The error text says to set `http.cors.allow-origin`, but it misses out the important `http.cors.enabled: true`

Working config: 

    $ grep cors elasticsearch-1.4.0.Beta1/config/elasticsearch.yml
    http.cors.allow-origin: "/.*/"
    http.cors.enabled: true
