Data extraction tool

I refactored data extraction and loading tool. There is ant build.xml file to create distribution jar automatically and instruction how to recreate Eclipse project directly from GitHub to inspect and expand source code if necessary.
From a functional point of view, only one feature was added. hivedb key allows modifying the prefix for exporting tables in Hive format. In Hive there is no schema, so table name prefix is simply separate database name. By virtue of hivedb parameter, it is possible to change schema name taken from the source database or remove prefix at all and load Hive tables into default database directly.
