Test setup / remove inline scripts

This PR is 2 parts. 

First add's the ember addon test setup. This makes it so within the addon you can run `ember test` and `ember serve` to work with a dummy ember app. Which makes testing that this works much easier :)

The second part is removing the inline script's that were being added via the blueprint. They violate CSP and the ember-cli-content-secutiry-policy is added by default so it would complain for people who add this to theirs. Now the blanket options and QUnit start are injected into their proper files dynamically at build time.
