Updated ember-cli, tether, and ember versions, and introduce bodyElementId option

We have updated to a new version of Tether that supports an option for specifying the element which Tether should move the positioned element to (the default is the body). For more details on that change, see shipshapecode/tether#204. Thanks to @pzuraq for his work on this.

This is particularly useful for Ember acceptance tests, which root the Ember app in the #ember-testing div. As of this release, you can now globally configure this. For example:

// config/environment.js
if (environment === 'test') {
  ENV['ember-tether'] = {
    bodyElementId: 'ember-testing'
  };
}

It is also possible to pass a bodyElement to a particular ember-tether component declaration.

This release also updated ember-cli and the versions of Ember we are testing against (now 2.4, 2.8, release, beta & canary).
