Added a quests system

This week we created a quest system and managed to add several options for tasks.

• friendly NPCs will spawn randomly on the map
  
  
  

• you can talk to them and take a task, completing which you can get a reward
  
  
  
  

• we have added a quest journal where you can track active and completed quests
  
• by default, the journal can be enabled on the "J" key
  
  
  

Now that we have the quest system, next week we will focus on adding more interesting quests.

• the wheels of the news van fell off
