v0.14

* Blender:

    * uses read/write/properties/createAs etc (initial)

    * worked around __proto__ to work in IE - all specs pass in IE 10

    * Gruntfile.coffee `build` for uRequire v0.6.7

    * subclass helper -(Backbone.X.extends) - works with Blender, instead of coffeescript `class extends`
