Release v2.0.0

✅ Added Bagman mode.

smashmodebm for free-for-all
smashmodetdmbm for teams

In bagman, a backpack will randomly spawn at player spawn locations. Collecting it will turn you into the bagman. While you are the bagman, every 5 seconds will give you a point/frag, but it will also add 25% to your knockback%. If an enemy kills you, they are turned into the bagman. If a teammate kills you, the bag will again start randomly spawning.

Additionally:
✅ Added 2s of invuln on smashmode spawn, which is canceled when the player shoots. The current invuln behavior is that the player takes absolutely no knockback on hits while it's active.
