title: rails t function showing i18n
body: <p>I'm working on my first refinerycms project and there is this line in the footer:</p>
  
  <pre><code>&lt;%= t('.copyright', :year =&gt; Time.now.year, :site_name =&gt; Refinery::Core.site_name) %&gt;
  </code></pre>
  
  <p>It's displaying this on my site:</p>
  
  <pre><code>i18n: Copyright
  </code></pre>
  
  <p>Where does the i18n come from and is the t function needed?</p>
  
  <p>EDIT:</p>
  
  <p>My /config/locales/en.yml contains the code below. Do i need to add something to this or would it best just to remove the t() tag?</p>
  
  <pre><code>en:
    hello: "Hello world"
  </code></pre>
