Metamorph

This patch update adds a keybind field to creative morph menu, added animation of body part transformations based on parent animated morph, and improved performance in the creative morph list.

Compatible with McLib 2.2. It doesn't mean that future versions of McLib would be incompatible, but older versions are most likely incompatible.

• Added Copy /morph command context menu to creative morphs menu (suggested by Centryfuga)
• Added confirmation to remove all morphs context menu item
• Added keybind field to morph panel in morph editor
• Added custom hitbox options to all morphs
• Added an option (enabled by default) to animate body part's transformations based on parent morph's animation progress
• Fixed some (like copy to recent) context menus not appearing in creative morphs menu
• Fixed morphs not updating after server updated the blacklist
