0.2 Graphical Update

overhauled the graphics for things i previously just threw together. Still a couple more to do. but for now it'll work.

similarly, entirely changed the game opening cut scene, its now a cute little animated comic explaining whats happening.

tweaked the difficulties again under the hood, made the final calculation harder on harder modes requiring more accuracy.

renamed the game from Icarus in space to just ICARUS and sprinkled lore.
