Upgrade ember-cli-babel

⚠️ Haven't checked to see if this breaks anything yet ⚠️

$ node --version
v0.12.18

CI needs to be updated to use Node 4 (this was the main breaking change in ember-cli-babel@6).

It looks like ember-inspector may simply drop this dependency, and I don't know of any other use cases, so I don't see much point in putting any energy into this. Simple tweaks to .travis.yml to use node 4.x and default npm don't seem to have done the trick (CI build stalled then terminated. Running npm test locally shows lots of No tests were run, please check whether any errors occurred in the page (ember test --server) and ensure that you have a test launcher (e.g. PhantomJS) enabled.).

I did get a kick out of this line of the output though...oh how time flies:
Future versions of Ember CLI will not support v4.8.7. Please update to Node 0.12 or io.js.

Dang, haha, I got it to pass by locking jQuery at 1.11 since there's an assertion that doesn't realize 1.12 is OK. Feel free to merge or close as you like. Shame on me if I goof around with this any more when I should be doing productive work :)
