[Freeciv-Dev] (PR#4023) switching tilesets in gui-gtk

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

As reported by somebody-or-other (Kenn?) for the gtk2 client...

If you start the GTK client with a non-iso tileset, then switch to an 
iso tileset and turn on the map grid it won't work.  This is because the 
line-drawing data was never initialized.

The patch is simple.
