* Add an app-wide context for global props.
We've been passing the `api` object down from the top of the react tree. With
16.x, there's now the ability to have context that can inject anywhere in the
tree. This creates a top level context provider that contains most of the global
variables we've been using (api, appData, ...). It subsequently cleans up some
of the routes and nested components.
- Bumps `react-dom` to 16.3.2 (to match `react`).
- Adds `enzyme-context-patch` for now. This is fixed in enzyme master, but there
has not been a release yet. Needs to be removed when that is fixed.
* Use a default inside appData for controllerNamespace
* Update syntax of if to use curly brackets
