co♻e: unittest framework for CODESYS

RC5 fixes Ticket n.o: #43, #44 & #46

Fixed Ticket 42/37

FB_TestResults, replaced;
57 IF StoringTestSuiteResultNumber = GVL_CfUnit.NumberOfInitializedTestSuites AND
58 GVL_CfUnit.TestSuiteAddresses[StoringTestSuiteResultNumber]^.AreAllTestsFinished() AND NOT
59 StoredGeneralTestResults THEN

With;
( If all test suites have finished storing their results, store the general test results )
57 IF StoredTestSuiteResults AND NOT StoredGeneralTestResults THEN

Which resolves the incorrect testnumbers in the results report
