Hotfix - New Perks, Explosions fixes and other technical improvements

[h3]New perks[/h3]

• Perk Bloodthirsty - Reduces cooldown of crew recovery if you get a confirmed kill
  
• Perk Combat Repairs - Reduces cooldowns of hull/sail repairs if you get a confirmed kill
  

IMPORTANT. Perk currently works ONLY on the vessel you used to enter combat - if you switch ships in battle you wont be able to use the perk on other ships.

[h3]Other changes[/h3]

• Explosion damage has been lowered.
  
• Important: due to new mast HP you will still lose masts if you are in the explosion radius, please make precautions. It will be fixed next week.
