Attempting a new fix for the MacOS Windows dissapear behind skymap bug

• This should still prevent most windows from disappearing behind the skymap just like my previous fix from 2017.
• The previous fix ended up making some alerts, modal dialogs, and other windows go behind "alwaysontop" windows, this fix should allow them to come to the top by adding those attributes to them too.
• This updated fix should still allow Ekos, INDI, and FITSViewer to become "independent" windows. This fix should also prevent them from vanishing behind the skymap when "independent"
• I added functions that will turn them into "independent" windows and back again as soon as you click "apply" or "ok".
• This fix can do nothing for the "About KStars" window or the "Configure Notifications" window which are not created by KStars and so they can still go behind the skymap. My previous fix could not address them either.
