* Fix: #3270
removes an unnessecary check which returned a double nil wich in turned causes a crash if systray doesn't have an attached window.
* Add iconIsInFlyout method to systray_windows
and use it to determine if the icon is in the
flyout or not when positioning an attached window.
* optimize the windows systray window positioning
we only need to get the systray bounds if
the icon is in the flyout area.
* Use correct behavior for placing the window
if the systray icon is visible in the taskbar the
window should be centered on the systray icon
otherwise the icon is in a flyout are and the
window should be placed in the corner.
Added comments to explain placement logic
* consistent placing of systray menu on right vs left click
* add PR info in changelog
