initial version of mixed mode for TestNG:

-added '-mixed' cmd line switch and mode="TESTNG|JUNIT|MIXED" ant task attribute

-when this mode is selected and some version of JUnit is found on the classpath then TestNG tries to automatically recognize the type of test and run it using appropriate test runner (testng for testng, junitcore for junit4/3 - if junit4 is found or junit 3 runner - if only junit3 is found)

-improved test results reporting for invoked JUnit tests
