Final Game Jam update

This is likely to be our last update before the Game Jam submission period ends. 

We've fixed some more UI keyboard/controller focus issues. A full-screen button (Select) has been added to the controller to match the keyboard functionality (Alt-Enter), and it has been added to the help page. There is now a button to not connect to an existing nearby post if you want to add a new one instead. When you are close to a post you will connect to it instead of placing a new post. If this will happen the post is now highlighted. When placing a fence you will now see a preview of where the post will go, unless you are connecting to an existing post which will be highlighted. It will turn red if you cannot place the post there. Animals have had some behavior updates. Background creatures have been adjusted.

There is still plenty more on our to-do list, which will be added after the Jam!
