Added # of tests executed to the final results

Right now the final output of the console runner is something like this:

10/10 assertions passed. Elapsed Time: 14.96 sec

Just for statistics purposes, it would be nice to also include the number of tests, something like this:

10/10 assertions | 4/4 tests passed. Elapsed Time: 14.96 sec

Could be valuable in some situations. I believe that it should be enabled depending on the logLevel given (to make it configurable & disable it by default), else the output of the console reporter could be a bit noisy.
