Subject: [PATCH] Create branches according to elasticsearch versions We create
 branches:

* es-0.90 for elasticsearch 0.90
* es-1.0 for elasticsearch 1.0
* es-1.1 for elasticsearch 1.1
* master for elasticsearch master

We also check that before releasing we don't have a dependency to an elasticsearch SNAPSHOT version.

Add links to each version in documentation
(cherry picked from commit 65d4862)
