Link to the official docs by default

[sivakumar-kailasam]

Since this addon is Ember specific, does it make sense to link to the official ember & ember data yuidoc when generating a blueprint? Like,

  "external": {
    "data": [
      {
        "base": "http://emberjs.com/api/",
        "json": "http://builds.emberjs.com/tags/v2.7.1/ember-docs.json"
      },
      {
        "base": "http://emberjs.com/api/",
        "json": "http://builds.emberjs.com/tags/v2.7.0/ember-data-docs.json"
      }
    ]
  }

what happens when Ember gets updated though? Or if I use an older version in my project? As a starting point this is definitely a reasonable default, I think.
One small remark: the base URL for ember-data should be http://emberjs.com/api/data/.
