Upgraded APIs: Flink (0.8) and HBase (0.98.x) + profiles

I had to create an hadoop.core.version variable to manage the fact that cloudera has different versions for hadoop-core and hadoop-common..
I think, we don't need the wrappers for HBaseResult and HBaseKey anymore.
The new API allows to process arbitrary objects and serializes them with Avro (will be changed to Kryo some time in the future). 
But you should double check if this is working.
