1. added wxEvtHandler::SafelyProcessEvent() and wxWindow::HandleWindowEvent() to correctly handle exceptions in even handlers in wxGTK

2. use HandleWindowEvent() everywhere as more obvious and convenient shortcut for GetEventHandler()->ProcessEvent(); also for consistency with wxGTK where it's required
