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

- Parts of "Implement optional parameters for the test results".
The following is implemented: Whether a test is skipped, failure message/type for a testcase.

- Moved the general test results (NumberOfTestSuites, NumberOfTestCases, NumberOfSuccessfulTestCases, NumberOfFailedTestCases) into the new test results struct ST_TestSuiteResults, which also containts the results for all test suites.

- Fixed adjusting of AssertFailureMessages from 252 to 253 characters (by removing an unnecessary space character)

- Added logging of all new extended/optional test result parameters to the logger

- Added report logic so that skipped tests are not included in the total amount of successful tests (NumberOfSuccessfulTests = NumberOfTests - NumberOfFailedTests - NumberOfSkippedTests
