Blockbuster 1.4.2

This is a small patch that adds few user requested features. Somebody might get excited for this.

• Added legacy compatibility for pre-1.3 director blocks (requested by NlL5)
• Added support for arm postures and item animations (suggested by RedComet2000)
  • Comes in effect after making a new player recordings (since some new data needs to be recorded)
• Added Hands field in player recording frame data structure
