Fix for issue #81: Reportal hadoop.bin.path Hive conf property is set incorrectly in Hive 0.12+

Changes:
- Updated the Hadoop core jar to 1.2.1 and the Hive jars to 0.12
- Removed some unnecessary Hive configuration code that was causing the hadoop.bin.path to get set incorrectly
- Removed a logging statement that would print out the entire hive.aux.jars.path for each Hive statement we executed.
