Cleanup mode
There are some segfaults by action( rs_action* methods) destructors caused by actions when closing the main window. These segfault can be fixed by detecting RS_GraphicView cleanup in action destructors.
A method to detect cleanup is added:
bool RS_GraphicView::isCleanUp() const;
whenever isCleanUp() returns true, action destructors should not try to cleanup, as entities may be deleted already.
TODO: We need a better solution probably by smart pointers.
