Added support for CTest awareness of the CDash version. This will help forward compatibility for both tools. Note that this changeset effectively makes the default to disable output compression. Now, to enable output compression, the CDASH_CTEST_VERSION must be explicity set to >= 1.6. Automated detection of the CDash version is the next step.
