0.333.4 - Twinkle Twinkle Little Rock

This is a hotfix release, fixing following bugs:

• Massdriver bullets fired at point-blank range tended to survive the impacts much more often than they should be.
  
• Fixed a number of typos in transactions.
  
• Enabled mip-mapping for background ring debris, so they don’t twinkle so much when you are zoomed out and they are just specks of dust.
