Feature Request - SpriteSets

SpriteSets

A new folder in your project, where each asset needs:

• A png sprite sheet
• A Json/XML file describing each animation frame and duration from multiple sets of pose(Ghabry Preffers JSON).

Then you can attach those special files to anything: Battlechars, charsets, Monsters, pictures, etc...
With that you can set up assets like:

• charsets with more than 3 frames, or custom size, or custom hitbox.
• Animated Monsters/pictures/facesets
• slower pictures with variable speed.
• etc...

one way to call it is instead of using on a charset the string "actor1" you could call "*spriteset/actor1.walk_poses"
