Fix the base map orientation, drop the city overlay, keep td.scn out of the editor

Browse Source 
The Geoportal images arrive with their first row at the north edge, which is
the opposite of what the default texture coordinates assume - the vertical
ones are now swapped, for the picker's base map and the orthophoto alike.

With the real map carrying its own detail as the view zooms in, the drawn
city markers had nothing to add and are gone, along with the coordinate
table behind them. Only the country's extent remains, to open the picker on.

-editor no longer inherits the scenery named in eu07.ini. That is whatever
was last driven, which has nothing to do with editing; without an explicit
-s the editor opens on empty ground.
