title: Local CSS resource in GM script not recognized
body: <p>I have a GM script that contains the following:</p>
  
  <pre><code>...
  // @grant          GM_addStyle
  ...
  // @resource       css my.css
  ...
  
  GM_addStyle(GM_getResourceText('css')) // the error occurs here
  
  ...
  </code></pre>
  
  <p>GM threw out this script from its <code>config.xml</code> (that happens occasionally) recently, so:</p>
  
  <ul>
  <li>I renamed the scripts folder to <code>/*.OLD</code>,</li>
  <li>created a new script with the same name,</li>
  <li>copied all files (<code>*.css</code>, etc.) from <code>*.OLD</code> to the new script folder, except the script file (<code>&lt;name&gt;.user.js</code>) itself,</li>
  <li>C&amp;Ped the code from <code>/*.OLD/&lt;name&gt;.user.js</code> to the newly created script file.</li>
  </ul>
  
  <p>Now it runs again but throws an:</p>
  
  <blockquote>
  <pre><code>Error: No resource with name "css"
  </code></pre>
  </blockquote>
  
  <p>Why this? The resource <em>is</em> declared above and <em>it exists</em> in the script's folder. (There's also no upper/lower case difference between the declaration and the actual file name.)</p>
