[1.1] [UI] [Suggestion] Warning when ending turn when you have idle cities / units
If you have idle cities or units when pressing end turn, I want the game to tell me "You haven't moved all your units this turn, are you sure you want to end you turn?". Or "Some of your cities are idle, are you sure you want to end your turn?". If you click no, it should center on something that is idle.
