Update 1.0.2

Changes

• Fixed an issue with tribute payments not being calculated correctly
• The (allegedly) corrupt city officials are now properly executed in the "Unrest in the City" event
• Made sure Great Pazuzu is actually paid for driving the disease demons away with His mighty wings
• Fixed a calculation in the "Very Ill Omens" event
• Made foreign cities more receptive to the player's gifts
• Changed the event selection function to make sure a Very Important Event always happens when it should
• Changed the famine calculation, which should hopefully fix the NaN issue. Let me know if it still happens!
  
• Fixed minor typos etc.
