Bug fixes — Nations Steam update #1867683

- fixed a lot of major and minor bugs, some of them causing crashes - added option to hide capital cities and settlement - improved AI - since now it should manage finances way better - fixed balance issues - since now playing as minor nations should be easier, and playing as major nations should be a bit harder. Also some law modifiers were changed - added two new administrative unit types: colonies and governorates. They may be useful in some conditions - difficulty modifiers were changed - since now they should impact the game much more - a foundations for the next update were made I am sorry for such a long period without updates, I hope the next update will be way faster. It is going to be focused on adding rivers and some basic decisions to the game. I hope you enjoy.
