P0-B8: Part 1421: Debugging, Improvements

I have made some minor improvements to the survival mode (On earthlike planets) in the game, and I have also written and uploaded a EULA (Which is required by steam before publishing).

I have also made some GUI changes to make it easier for the player to set their initial conditions for the modular quests.

The new quest is going very well. I have added several new features to the quest system for this quest alone.

I also fixed several minor issues with the new quest system.

I have also made changes to the procedural content creation system that allow cities to be created on non-earthlike planets. These cities are more rare than on earthlike worlds, and survive within a shielded dome.

This was done to make non-earthlike worlds easier to survive on for players.

I still need to make adjustments to the probablities, etc, with procedural content creation system to keep things balanced.
