New: Basescape: Can place buildings next to uncompleted-buildings. (Building-Queue)
This feature can be turned on/off with allowBuildingQueue in options.cfg.
Default is OFF!

Instead of showing "Queued" to such buildings (as in UFOextender's "Base Building Stacking") it shows the days left to complete. (so it is a sum determined by the queue)
