Aircraft wander aimlessly limitlessly

[Caydr]

It seems that all types of aircraft have this problem. Suppose you build a construction seaplane - given about 5 minutes it will have wandered so far from its point of construction that it'll probably have been picked off by your enemy or enemies. Aircraft need to have their wandering distance limited to their maneuverleashlength. This goes for dontland=1; (or what that code's been changed to recently) units as well, which, since they can't land *anywhere*, can start in one corner of the map and be wandering around in the opposite corner inside of 10 minutes sometimes.
