Post Jam Update, 1.1

Fixed login and scoreboard. Finally, the game shouldn’t crash.
Added 1 gun mode, for players that want simpler controls with just a mouse.
Added 2 player mode, for players with 1 or 2 gamepads. Split the 2 guns between two players with two gamepads, or one with a gamepad and the other with a mouse.
Updated enemy pathing. When enemies retreat, they circle a bit closer to make it clearer that they keep coming back until you destroy them.
