Fix usage with Chrome Harmony.

Currently, the test suite fails when running with
`chrome://flags/#enable-javascript-harmony` enabled.

All of the failures were due to duplicate declarations, which apparently
fails when running with Harmony features enabled...
Merge pull request #4856 from rjackson/harmony-fixes

Fix usage with Chrome Harmony.
Broccolify #1.
Add bower and remove broccoli-bower.
Fix issue with returned module name (from path).
Update qunit_configuration from latest EmberDev.
Make `?package=ember-metal` work properly.
Add defeatureify to output.
Compile all files in test tree.
Do not wrap non-test build in eval.
Add uglify.
Do not duplicate the package trees.
Update Brocfile to handle package deps.
Move vendored libraries into packages.
More tweaks to Brocfile.js.
Refactor Brocfile vendor package loading.
Move ember package to packages_es6.
ES6ify ember package.
Include ember package in Brocfile.
Do not export Ember.Application from ember-runtime.

This is causing an issue with load order. If ember-application package
is loaded first, then ember-runtime is loaded we will actually clobber
the correct Ember.Application with the completely skinnied down version
in Ember Runtime.
