Version 0.99.26

Hi everyone,
Here is a balance/changes update.

• Minotaurs now have Armor Breaker ability.
  
• When hero is on fire, his armors' durability reduces.
  
• Made some difficulty adjustments after level 15-20. The game was getting a bit too much difficult .
  
• Helping towns during epidemic is easier now. Every potion sold during epidemic reduces the epidemic time by 3 days instead of 1 day.
  
• Helping towns during famine is easier now. It needs less food to stop famine.
