Save System + QoL + Map Gen

It's been awhile since I've worked on this game, But with some much-needed updates. I think it will be a lot smoother to play. 

As you can see by the new images, there's now people who walk around the colonies, along with paths that develop over time. additionally, I've done a little bit of buffing to the food system, as it was essentially impossible to survive winter before. 

I've also implemented a save system, allowing for you to continue your path as colony. 

Also, rivers! 

Sadly, the tutorial has kind of broken due to some additions to the game (mainly the save system), so I've removed that temporarily. I hope to bring it back in the next update. 

Lastly, there are a few graphical changes in the menu that allow it to automatically have dark mode, along with better Mobile support (even if it's not officially supported). 

Thanks for reading.  Let me know what you think I should add / update.
