Kevin Ansfield 8710f5f532 Added animation of sidebar between main and contextual menus ... refs https://github.com/TryGhost/Team/issues/1149 - added `ember-css-transitions` library that provides a modifier that adds/removes classes used for animating elements in and out, automatically creating a clone for destroyed elements - added a wrapper class around the `main` and `design` nav menu contents so they could be individually animated - used the new `{{css-transition}}` modifier to animate the sidebar menus in/out - ensured main menu doesn't animate on first render of the parent `<GhNavMenu>` component so there's no animation when Admin is loaded		2021-10-20 13:04:05 +01:00
