Happy weekend, Gladiators!

This patch contains :

• New mid-sized boss! Can you beat him ?
  
• Nerf the mace and fork. NPCs should feel less powerful when yielding them.
  
• Disable the camera zoom. Controls were incompatible with the zoomed-out camera, it needs a separate scheme.
  
• Fix some minor physics calculations.
  
• Nerf minotaur damage.
  
• Lower traps stickiness.
  

Let me know how the balance and new content feels.
Keep slaying, Gladiators!
