title: Frontend Plugin options not displaying for Extension Builder
body: <p>I created an extension with a frontend plugin using Extension Builder called "Planner". </p>
  
  <p>The plugin is listed while editing the page content (Inserting into the page), however, the <strong><em>plugin options are not being displayed.</em></strong> </p>
  
  <p>The actions created in the controller are List, Index, Show, Edit, New. 
  The folder structure in conf/ext also seems fine. 
  The table table tx_planner_domain_model_planner has also been created. </p>
  
  <p>Where did I go wrong ?</p>
