I have set the buildupscavangers to 1,
so only one can build, not a group....
I intended this originally anyways.

Reworked the buildingselection-marker.

the FOW-Circle is now a "Circle"
(I know Matt, that you could make the nicer looking Fog,
but I really dont want to spend too much calculationpower on that
effect for now, as I also need to turn the fog off during development too)

Now I will make a cancel for the buildupline.

Should they cancel the unit clicked on, or the last unit
in the row?

The thing with the action is a good point,
I might alter the cursor, so that it shows the current selected action.

PS, I will upload the next demo, whenever I have more progress,
so that the demoversions will not change so quickly,
But the feedback is very useful though.
