elasticsearch 1.0.0.RC1

I've successfully upgraded Elasticsearch from 0.90.7 to 1.0.0.RC1 with this formula.

The new command line flags are explained here : http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/_system_and_settings.html

It has been install in `/usr/local/Cellar/elasticsearch/1` instead of `/usr/local/Cellar/elasticsearch/1.0.0.RC1`.
I don't know if it's an issue, but I don't know Homebrew enough to fix this.
