SetUpTestCase & TearDownTestCase are called multiple times per test case

[ftrofin]

Because each test method is registered separately, when I want to run a whole test case from the Test Navigator, multiple calls to RUN_ALL_TESTS() will be made (one for each test in the test case). This has the undesirable effect that SetUpTestCase & TearDownTestCase are now broken, instead of being called once per test case, they are called once per test method (just like SetUp/TearDown). I don't know how to fix this, otherwise I would have created a pull request :-)

The gtest filter allows using a test case name as a valid filter and has the desired result - runs all the enabled tests in that case. The problem I couldn't figure out is how to create a selector for the test case itself (as opposed to individual methods) that is invoked when I click the "play" arrow in the Test Navigator on the test case.
