Update 0.5 (WIP)

I had to push the release date back a couple of days, now the 11th of July, because of the steam summer sale. This will give me a little more time to add features to the release build. Here's my todo list.

• season leaderboard
  
• achievements
  
• in-game music
  
• mouse controls
  
• vehicle collision improvements
  
• ai tweaks
