Art Update Almost Finished!

Hello Warfarer! With a bit of work, I've doubled the amount of sprites available for the citizens of Arath while also touching up the old sprites. Once the results for the game jam are out, I'll update the game with the sprites as well as with some gameplay changes (hints of a bigger update coming after). 

Here's a comparison between the old sprites and the new. You can see that the sprites still repeat often, but that's a minor issue compared to many other gigantic holes in the game so the fix'll come later.
