FlashWindow() can be used to bring user attention to application
in background. Right now in LO it has implementation only for
Windows. Here some new cases were added when flashing is used:
* dialog window did open
* document loaded
* LO started
Some redesign of previous solution is also performed: no manual
search for top window, let's reuse existing code.
Changed behavior for bringing LO window to foreground: it is made always and not depending on current value of NewDocumentHandling:ForceFocusAndToFront. It has no sense to tweak this behavior: if user clicks on document in file explorer, LO should came to foreground, no exceptions.
