Fixed invalid paths in servicestack\setup.xsp.py
Cleaned up version refs in README.md
Updated `queries` request in `servicestack`

Updated the `queries` request handler to honor the FrameworkBenchmark's
specification that requires multi-db requests "counts" value to between
1 and 500.

Also changed the TODO about running tests in parallel.  Parallel tests
are acceptable, but need additional testing to verify performance gains.
