[Freeciv-Dev] (PR#8563) wonders have no graphics

The gtk2 client puts unit and building graphics into the citydlg.

But wonders have no graphics.  All they have are little blue squares.  I 
think this is what's actually included in the tileset.  Instead the 
tileset shouldn't include these sprites at all.  The client can check 
for the NULL sprite and simply leave the graphics out.

Of course in the long term we'd like to have some wonder graphics. 
Anyone want to draw some?
