1. Fixed the trailing tabs in actual output files.
2. Removed defunct system test scripts, classes, methods and code blocks.
3. Complete implementation of queries via sqlline:
  - We had pieces of sqlline in the code base, but they are hopelessly outdated.
  - Improved the way queries are submitted via sqlline.
  - The new implementation includes a full-blown verification mechanism that cleans up output files sqlline produces.  This allows the streamlining of existing verifications of JDBC query results.
4. Eliminated spaces in actual output files.
