Feature/ingest voices

Hi @NYULibraries/hydra 

So, I am pushing this up with the hopes that someone can help me out with the cucumber testing.  I ingested the data by doing 
bundle exec rake ichabod:load['voice','http://discovery.dlib.nyu.edu:8080/solr3_discovery/core0/select']

I could see it in the development instance of Ichabod. I then tried to change it to test environment by creating an environment variable, RAILS_ENV = test. I tried to load the data again. I ran cucumber tests again search.feature and collection_facet.feature and the Voices steps for both features keep failing. Can someone help me out here?

Thanks.
@eshadatta You can DRY this up since it's identical to the Rosie one.

Delete one of the redundant files and rename the other one to `vcr_steps.rb` and remove all the `Around` statements and just replace with

```ruby
Around('@vcr') do |scenario, block|
  using_vcr_cassette("#{scenario.feature.title}/#{scenario.title}") do
    block.call
  end
end
```

And then you can change the tags in the features to just be `@vcr`. No reason to differentiate the tag names if they're doing the same thing.
