More loyal generation of the world! New algorithm for saving gameplay!

1. The game will now have a more loyal generation of the game world. Now it will be easier to start a new game! On the first location will not spawn animals, and rare mobs (fat man, spitting poison, etc.). Also, the first location will no longer spawn a car with an active alarm system. And now the first location will never be a "swamp".
2. New game saving system! Previously, the game process was saved automatically when the player enters the base. This could harm the player, since he does not always return to the base full, and this killed him, and as a result, the player continued the game with a "dead loop". But now, the game is saved manually. Now the player just needs to click on the virtual button (on the interface) to save, at any time they need. The main condition to make a save-the player must be on the base.
