title: Doesn't Picasso support to download images which uses https protocol
body: <p>Hello I am using the <code>Picasso</code> library to download the images from URL. </p>
  
  <p>URL : <a href="https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t1.0-1/s200x200/1472865_191408954385576_14109897_n.jpg" rel="noreferrer">https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t1.0-1/s200x200/1472865_191408954385576_14109897_n.jpg</a></p>
  
  <p>URL is using https protocol, here it is not working for me to download the images of https protocol using <code>Picasso</code>. </p>
  
  <p>Doesn't it support to download the images which uses https protocol, it worked for me only if I use http proctocol ?</p>
  
  <p>Here I am trying to get bitmap which is using https protocol </p>
  
  <pre><code>com.squareup.picasso.Target target = new com.squareup.picasso.Target() {
  
  @Override
  public void onBitmapLoaded(Bitmap bitmap, LoadedFrom loadedFrom) {
      userProfile.setBitmap(bitmap);
      // call the Web API to register the walker here
      new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
          @Override
          public void onTaskCompleted(String jsonResponse) {
             Log.d(TAG, jsonResponse);
          }
      });
  }
  
  @Override
  public void onBitmapFailed(Drawable drawable) {
      userProfile.setBitmap(null);
      // call the Web API to register the walker here
      new AudioStreetAsyncTask(getActivity(), userProfile, getString(R.string.registration_processing_message), new TaskCompleteListener() {
          @Override
          public void onTaskCompleted(String jsonResponse) {
             Log.d(TAG, jsonResponse);
          }
      }).execute();
  }
  
  @Override
  public void onPrepareLoad(Drawable drawable) {}
  };
  
  Picasso.with(getActivity()).load(imgUrl.toString()).into(target);
  </code></pre>
  
  <p>Any idea ?</p>
