* test/testcase.vala (TestCase): Make the test case's main loop accessible to subclasses so they are using the same one we are. (TestCase::async_result): Use GLib main context rather than GTK+ main loop so that test cases with async methods work even when GTK+ not present. (TestCase::async_complete): Ensure the main loop is woken when an async test completes so the test case doesn't block if it loses the race with async_result();
