Updated Apache Hadoop to 2.5.0

Updated 0.94 branch to use with Apache Hadoop 2.5.0 version as described in the Apache HBase documentation: http://hbase.apache.org/book/configuration.html

This workaround is required for integration of Apache Nutch with Apache HBase 0.94.24 and Apache Hadoop 2.5.0.

Recent Apache Nutch from 2.x branch (https://github.com/apache/nutch/tree/1860b833cb28c7e5f5cdf3909f86dd0ab9985d1d) depends on Apache Gora v0.4 which works only with Apache HBase 0.94.x.

Build:
# mvn clean install assembly:single -DskipTests
