[Feature] A traitor Katana

Some potential sword abilities:

• Slash- Melee attack that hits the tile in front of you, as well as the ones to the left and right of that. Default attack
  
• Stab- Melee attack that extends two tiles away from you. Pierces through and continues to damage anyone behind the first target
  

• Spin- Melee attack that hits every tile around out. No cooldown, but too frequent use leaves you first stumbling dizzy then stunned if you continue
  
• Lunge- A quick dash. Very low cool down
  
• Parry- A few seconds in which Melee attacks are blocked, ranged attacks have reduced damage
  

I like these ideas for special attacks, they seem pretty doable since the new mining tools have multi-square-attack stuff (i actually think more stuff like this applied to existing weapons/maybe craftable ones would be good but shh)
