Breakage on Ember 2.12

[bj-mcduck]

I'm getting the following breakage on upgrading to Ember 2.12, and it seems to be coming from something within this package.

Cannot find module '/Users/brandonmckay/Foodee/StarFox/bower_components/ember/ember-template-compiler.js'

Updated the plugin to 2.12.1. Please let me know if this fixes the issue.
