0.12.0

• <ReactGridLayout> will no longer animate so severely on mount. See #212.
  • If you are using <WidthProvider>, you may notice that the container's width still shunts on mount.
    If you like, you may delay mounting by setting measureBeforeMount={true} on the wrapped element. This
    will eliminate the mounting animation completely.
  • If you enjoyed the old animation, set useCSSTransforms={this.state.mounted} and toggle the mounting
    flag. See 0-showcase.jsx for an example.
• Set more permissive version ranges for <Draggable> and <Resizable> dependencies, as they are now stable
  and will only introduce breaking changes on major version ticks.
