Fixed issue in testrun.c where specifying testsuite would find the tests in the corredt directory but would still try to execute them out of ./t
Added test status tracking and summary report at end of test run cycle to make it wasy to see what passed, skipped and failed at a glance, similar to MTR.
Changed testrun.sh slightly to return same code out of testrun.sh as the test that was executed when only a single test was run.
