title: Error while taking pictures using MeteorCamera.getPicture() while testing on a laptop
body: <p>I am working to add a photo ability to my app using Meteor's mdg:camera plugin.  For now, I don't have any PhoneGap devices setup, so I am testing on my laptop.  I thought I read somewhere that the Meteor implementation would fall-back and use a simple file dialog when a camera wasn't available, but when I try to run the following code on my laptop:</p>
  
  <pre><code>var cameraOptions = {
      width: 800,
      height: 600
  };
  
  MeteorCamera.getPicture(cameraOptions, function (err, data) {
      if (err) {
          console.log(err);
          // TODO Need to handle the error
      } else {
          if (!this.photos) {
              this.photos = [];
          }
  
          this.photos.push({ submitted_by: Meteor.userId(), submitted_on: new Date(), photo_data: data});
      }
  });
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>Meteor.makeErrorType.errorClass {error: "unknownError", reason: "There was an error while accessing the camera.", details: undefined, message: "There was an error while accessing the camera. [unknownError]", errorType: "Meteor.Error"…}
  </code></pre>
  
  <p>I would actually like for users to be able to upload photos via the same button when using a laptop.  For what it's worth, I actually do have a camera built-in, and I am developing on a 15" MacBook Pro.</p>
