[2.0.10] Holding control hides building area

[aeryen]

When having e.g. stone bricks in hand and pressing the control key, the building area is hidden (wrongly?). This did work with 1.x and is really unfortunate as I had the in-/decrease building size controls mapped to control+mouse wheel to choose the size much quicker.
All other controls containing "control" are from the defaults.
