Bumping tag version so bower install pull correct version

References #10. Currently bower.json points to v0.1.2 tag -- which is behind master. Increasing version to 0.1.3 and adding a tag

```git tag -a 0.1.3 -m 'Adjusting version so bower install pulls updated version'```

Will make bower install ember-testing-httpRespond --save pull a version compatible with the latest version of Ember.
