title: VSCode plugin VSCode-PHP-Format not working
body: <p>I start using vscode less than a month. Please forgive me if this is a dump question.</p>
  
  <ul>
  <li>OS: OS X 10.11.3</li>
  <li>VSCode: 0.10.6</li>
  <li>Plugin: <a href="https://github.com/kasik96/VSCode-PHP-Format" rel="noreferrer">VSCode-PHP-Format</a> (download via git clone)</li>
  <li>Extension path: ~/.vscode/extensions/VSCode-PHP-Format</li>
  </ul>
  
  <p>I restarted VSCode, open php files, but do not see "Format Code" on the right click menu.</p>
  
  <p>Any idea how to debug this? Right now I don't even know if the plugin load correctly.</p>
