New Port: textproc/kibana42

Repo copy textproc/kibana41 to textproc/kibana42:

• Update PORTVERSION, PKGNAMESUFFIX, and distinfo for 4.2.1 and leave the variables conditional for the upcoming textproc/kibana43 slave port.
• Added https MASTER_SITES as a first option.
• New versions rely on node 0.12, change RUN_DEPENDS accordingly.
• Copy the config file before deleting directories, as it will also delete the config file.
• kibana.in: New kibana has to be launched in the different way, reflect that in rc script.
• kibana.in: New kibana can write to log file by itself, delete all output redirection magic from rc script.

Kibana is an open source (Apache Licensed), browser based analytics and search
dashboard for Elasticsearch. Kibana is a snap to setup and start using. Kibana
strives to be easy to get started with, while also being flexible and powerful,
just like Elasticsearch.

Kibana 4.2 is compatible with Elasticsearch 2.0.x.
