This patch update adds a couple of neat features and fixes.

Compatible with McLib 2.2.1, Metamorph 1.2.5 and Aperture 1.5.2. It doesn't mean that future versions of Metamorph and Aperture would be incompatible, but older versions are most likely incompatible.

• Added body_yaw and roll properties to /record clean and /record process commands
• Added support for nested animated morphs for morph action's animation duration marker
• Added Update scene after saving option (suggested by gewenzsko)
• Added Item scale and Cape options for model limbs
• Added new default cape model
• Fix crash with playback button GUI (reported by 1Deni)
• Fix record button not working in the standalone player recording editor (reported by gewenzsko)
