Email requests are responded to with corresponding package

Is there a reason you're using interpolation syntax here as `subject: "#{@package.subject}")`? In your `package_request.html.erb` you're using

```ruby
 <%= link_to "twitter", "http://twitter.com/#{ @package.twitter }" %> | 
<%= link_to "github", "http://github.com/#{ @package.github }" %> | 
<%= link_to "blog", "#{ @package.blog }" %> |
```
