Fix parsing of custom namespace routes. Transform class names, removing dashes and capitalizing each word/route part so a route path of `widgets/recent-posts` becomes a collection with the name `WidgetsRecentPosts`. Correct parent route part when routes are longer than expected, reversing parse direction.

Add QUnit tests: verify that wp-api loads correctly, verify that the expected base models and collections exist and can be instantiated, verify that collections contain the correct models, verify that expected helper functions are in place for each collection.
The QUnit tests rely on two fixture files: `tests/qunit/fixtures/wp-api-generated.js` contains the data response from each core endpoint and is generated by running the PHPUnit `restapi-jsclient` group. `tests/qunit/fixtures/wp-api.js` maps the generated data to endpoint routes, and overrides `Backbone.ajax` to mock the responses for the tests.
Add PHPUnit tests in `tests/phpunit/tests/rest-api/rest-schema-setup.php`. First, verify that the API returns the expected routes via `server->get_routes()`. Then, the `test_build_wp_api_client_fixtures` test goes thru each endpoint and requests it from the API, tests that it returns data, and builds up the data for the mocked QUnit tests, saving the final results to `tests/qunit/fixtures/wp-api-generated.js`.
Add a new grunt task `restapi-jsclient` which runs the phpunit side data generation and the qunit tests together.
