[TOGoS] [0.17.4] Default terrain size is limited after playing "Tight spot" campaign

[caer]

1. Steps to reproduce
- Start a new Tight spot campaign (Play > Start campaign > Tight spot)
- You don't need to play, but you need to "Restart" the game from the menu at least once
- Exit the Tight spot game
- From the main menu, now go to Play > New game
- As a new user you don't notice, but if you go to the "Advanced" tab the Map Width and Map Height are now set to 50 (see screenshot 1)
- Start the game by clicking "Play"

2. What happened?
See screenshot 2.
As a new user you now think that you are playing the most default setting of the game, but the map is actually a 50x50 square, so you can't do much (no resource).
The bug is that playing the Tight spot campaign should not have set a map width and height in the default map generation settings.
