Add a convenient wxREGISTER_UNIT_TEST() macro.

This macro can be used to easily register a test following a standard naming
convention in both the global test suite and the test suite with the same name
as this test instead of having to use 2 different cppunit macros to do the
same thing.

+// global unnamed registry so that it is ran by default and a registry with the

+// Notice that the name shouldn't include the "TestCase" suffix, it's added
+// automatically by this macro.

+// Implementation note: CPPUNIT_TEST_SUITE_[NAMED_]REGISTRATION macros can't be
+// used here because they both declare the variable with the same name (as the
+// "unique" name they generate is based on the line number which is the same
+// for both calls inside the macro), so we need to do it manually.
