Patch PreAlphe 0.6

I completely reworked the thirst system and added a new building. Before the thirst system worked like this: if the current event is thrist people go "no" and die. now it is very different and way better. the bar represents a little more than half of the houses you currently have. if they are not near water they will say "no water sir" and retract from the bar. If this bar is empty those who dont have water will die. For the new building there is a water through. it gives water to those who are in need of it. It only takes one person to build but there are some things you need to know. when you first build one it will be empty. you can fill it by clicking and holding on the water until the green bar is somewhere around a quarter filled. then you can release above the through. there is a max people that can feed off of a through but you can upgrade it. finnally it will get emptied by the flood.
