Minor joystick event handler finding refactor.
Remove the `evthandler` member and `Attach()` method from `wxSDLJoy`. Add the `GetJoyEventHandler()` method to `MainFrame`, which returns the window in focus, or the panel if the option for joystick background input is enabled. Remove the handler parameter in `wxSDLJoy::CreateAndSendEvent()` and call `wxGetApp().frame->GetJoyEventHandler()` to get the handler. Signed-off-by: Rafael Kitover <rkitover@gmail.com>
