Christmas Update - v0.5.532cae4

This update includes some new objects, as well as a new track. At the moment the team's focus is on the upcoming online multiplayer update, so this update is smaller than usual.

• Added a new track: WinterTyme.
  
• Snow tracks (Snoogy, Snorge and Polarius) got updated with the new snowy variants.
  

• Added some Christmas cheer to the Main Menu!
  

• Added new snowy variants for Fir Tree, Pine Tree, and Bush.
  
• Added static cars, vans, trucks and trailers.
  
• Up and Down arrow keys can now be used to cycle variants in the New Object tool.
  
• FIXED: Hay bales now correctly follow the terrain.
  
• FIXED: Phantom AI lines no longer sometimes remain when loading a track.
  

• The main menu sometimes experiences distortions or other rendering issues - changing resolution, or restarting the game may rectify the issue.
  
• Occasionally, when in Windowed mode, changing the language multiple times in quick succession can shrink the game window.
