Request: Release a version that includes ember-mocha 0.14.0

Looking at master's package.json, I was expecting an `npm install ember-cli-mocha` to give me ember-mocha@0.14.0 (including the new testing api). 

Here's what my npm installed package.json looks like
```
  "_from": "ember-cli-mocha",
  "_id": "ember-cli-mocha@0.15.0",
  "dependencies": {
    "ember-mocha": "^0.13.0"
  },
  "version": "0.15.0"
```
