Blockbuster

This patch update fixes a couple of bugs.

Compatible with McLib 2.3.1, Metamorph 1.2.7 and Aperture 1.6. It doesn't mean that future versions of Metamorph and Aperture would be incompatible, but older versions are most likely incompatible.

• Added a feature when duplicating a scene, all player recordings will be renamed using rename prefix algorithm to avoid overwriting player recordings from previous scene
• Added a feature to pack manually models into Blockbuster's jar (see assets/blockbuster/models/user/ folder)
• Added anchor point option to structure morph
• Added support for loading n-gons in OBJs models
• Added shadow option to image morph
• Removed eye height animation to being laggy
