This addresses Icepack #309.

• This includes an upgrade to the test reporting by removing the RUN outcome and doing a more careful job of defining and counting the results.

• Unique filenames are now generated everytime report_results.csh is run. Prior to this, running report_results.csh multiple times in a test suite would just overwrite the same detailed wiki page.

• report_results.csh now automatically runs results.csh. Prior to this, it did not. To turn off the feature, report_results.csh -n can be invoked.
