Interface update v0.1

Made it fully compatible with the working branch. This creates a new interface, with the "escape" key menu, as well as a sidebar containing the necessary information on the kids once the variable $UI == "game" and not "start" Just like was already written for the StoryMenu passage.

Basically, it should look alright when you start, single passage in the middle. Once you then actually start the game, the side panel appears and provides you with the necessary information. I could add a button to manually remove/add it in the Escape menu perhaps. Would provide the player with some customization options.

I did encounter some errors when trying to pick and choose the kids for you in the start, but I imagine those were there beforehand?
