Title: Selectable version of Hive

I made the hive version selectable, because the installation of Hive fails on a Hadoop 1.0.3 without a specified version of Hive. To stay compatible with the old implementation I selected Hive version 0.7.1 as default, because this is the first runnable version on your default Hadoop version.

In theory EMR supports to install multiple versions of Hive and to run scripts on them, but I found no way to integrate that without a complete rewrite of the installation of steps. Probably I can try that, if my time allows me.

Here is an overview of allowed Hive versions on different Hadoop versions: [EMR documentation](http://docs.amazonwebservices.com/ElasticMapReduce/latest/DeveloperGuide/UsingEMR_Hive.html#UsingEMR_SupportedHiveVersions)
