Update /godmode to use JourneyMode Godmode power.

- Previous Bouncer checks for GodMode (namely, Hurt) were removed.
- The command now uses the GodmodePower from core Terraria
- The toggle powers (which this command will now make use of) are now
  reset on disconnect to prevent accidentally "gifting" godmode to an
  unsuspecting player.
