Day 9 and 10 of implemenation 18.-19.7.2021

Added spawning area, so it resizes with the map and makes future spawning of objects simpler. 

Added basic gui, can now exit the game and replay the game after all players are dead. 

Also in the main menu you can now choose skin of your character and amount of players playing the game. That was quite tricky to implement and link everything properly with sprite library and resolvers.
