Update v0.6.89ed850e

A small update to push the upcoming AI updates in before the multiplayer patch! Happy New Year from all of us 🎆

• Significant updates to the AI logic, to make them faster (improvements to their overtaking ability will come later).
  
• Some further updates to the AI pitting logic.
  
• Made the "AI Skill" slider more accurately reflect the AI skill level.
  

• FIXED: Going to Editor, and using the Up/W keys, no longer prevents you joining a race with those keys when returning to the race menu.
  

• None.
