Version 2.b update! (just a small one)

This update changes the character sprite to be 8-directional, so it looks nicer when you're aiming diagonally. If you bought the source file and felt like 8-directional aiming would really help make your game better, now the code for that is in place!

(And yes, that's the only thing that was added in the 2.b version. If you like the old player sprite, you don't miss out on a lot of stuff if you don't update.)
