Feature: Show buildable terrain

[Decimator]

Some of the mountainous maps would benefit from a view mode that shows where structures would be built. A simple grid with red lines on areas that the structure currently selected for building will not fit would save time and make it less frustrating to play on a mountainous map.

F2 currently does something like that, although its not _that_ easy, because there isnt a globel "can build" thing.

A place might be too steep/rough for a large building, but could be leveled for a small one...

possibly a grid inficating the red/gold/green of the building attached to the f2 view if you are in the process of trying to build something then?

I suppose I could add something like that to the F2 display.
