Version 0.76.07

Hi everyone,
This is a small balance update.

• Enemies don't get Diseased/Grim Plague modifier at the first level for a more beginner friendly experience. Since it restricts the hero from entering towns, it presented an unintended challange for new players.
  
• Reduced the negative effects of Itchy Skin, Delusion and Wanderer's Flu from 40% to 30%.
  
• Book prices are increased by 50%. It is now more profitable to sell them at the alchemist's tower.
