Unit combat ticker displays

@freezy: We have tool-tip displays of combat tickers for naval units (both bombarding and melee combat), rockets in flight, artillery (bombarding and melee), and all other ground units engaged in melee combat. This is a great feature, and very helpful when a player is making a variety of decisions in a hurry.

That said, is there some rationale why this feature does not apply to aircraft units on patrol? Knowing when the 15-minute patrol ticker expires for aircraft units can be important for a variety of reasons, and currently the only way to get that data is to click on the patrolling aircraft unit icon ---- which sometimes incidentally moves the unit and resets its patrol ticker . . . .
