Comment 1 for bug 1218369

A reasonable sequence of choices would be:
- New empty map (1), new random map (2) or load a map?
- if 1: which world type, what size? then: With which terrain type (out of 16) shall the map be prefilled?
- if 2: the dialog we currently have. It contains everything that is necessary.
- if an existing map is loaded, no further decision have to be made
