Add json generation

[ghost]

I added a simple json animations generation.

The json format is the one used by:

• my animation software: https://github.com/devnewton/nanim
• my games: http://newtonadventure.bci.im and http://en.geekygoblin.org/ned-et-les-maki/

I'm also going to write an animation loader for phaser.io for this format.

Sample here: https://github.com/devnewton/newton_adventure/blob/master/game/data/default_level_data/bat.json

Hi. Thanks for the contribution. This would be a very cool addition.

Is this a standard format? If so, please provide a link to the specification(s).

I would request that you please update the README and provide a link to instructions on precisely how to use the resulting JSON in a game. Also provide a link "How to use" next to the save as JSON in the html file.

Thank you, Gaurav

Hello,

It's not an ISO/ANSI/... standard, but I will add some documentation.

I also wrote an xml exporter using Starling Texture Atlas format which is pretty popular (Starling, Phaser, Texture Packer...) and already has a nice documentation: http://doc.starling-framework.org/current/starling/textures/TextureAtlas.html

This sounds interesting. Any updates on this one ?
