Vadim Zeitlin 87ecf894e9 Convert simple GUI unit tests to use Catch directly
Get rid of the CppUnit compatibility macros in the GUI test files not
requiring any special handling: replace the test suite classes with Catch
fixtures, setUp()/tearDown() with the ctor/dtor and CPPUNIT_ASSERT_XXX()
with CHECK().

Tests using wxUIActionSimulator don't use WXUISIM_TEST() any more but
check EnableUITests() at the beginning of the test itself instead.

The pseudo test PseudoTest_Inversed in the wxSlider tests is replaced with
GENERATE() rerunning the tests for both normal and inversed sliders.

No real changes.
