title: Cordova missing cordova_plugins.json file. Have added it but still getting error
body: <p>I have just started a Cordova/Phonegap 2.0.7 project. All is going well but when I test in a browser I get the message:</p>
  
  <pre><code>MLHttpRequest cannot load file://localhost/~~~/www/cordova_plugins.json. Cross origin requests are only supported for HTTP. cordova-2.7.0.js:6410
  </code></pre>
  
  <p>I searched SO and found that this is a common bug and to just add a blank file name <code>cordova_plugins.json</code> to the <code>www</code> folder. I have done this but the error persists. </p>
  
  <p>On top of this I also get a Failed to Load resource error for a file</p>
  
  <p><code>file://localhost/!gap_exec?1368772098759</code></p>
  
  <p>and I have no idea what it is. </p>
  
  <p>I have not added any plugins to the project yet but am retrieving data via JSON with a small JQuery script. I am also using JQuery Mobile.</p>
  
  <p>Would anyone know how to remedy this at all?</p>
  
  <p>Thanks!</p>
