0.6.0

• Upgrade to ember-cli 3.0.0
• You can now actually view the app at http://localhost:4200/app. This isn't the recommended way since it doesn't merge in MI.options, but sometimes may be required for testing.
• If apps referenced local files via <img src="./img/*.png">, etc, these wouldn't show up in the preview because we weren't serving ./img statically. We eventually want to change the directory structure so that all statically served files are in one place, but in the meantime we've whitelisted $root/img/ and $root/style.css.
• By default, newly generated apps wouldn't render in capturama due to a typo; this has been fixed.
