Very hard to put down buildings in Paths model

[ToonTalk]

At first I thought it was broken. But then discovered one needed to click very fast. The following code toggles the existence of a building on every tick.

to check-building-placement
  if mouse-down?
  [ask patch (round mouse-xcor) (round mouse-ycor) [
    ifelse pcolor = red
    [ unbecome-building ]
    [ become-building ]
  ]]
end

I suppose for ordinary duration clicks there is a 50% chance of them working.

Also I suggest the Interface include some text mentioning that one can put down buildings instead of only relying upon careful reading of the Info tab.

Nice model, by the way.
