Use the same UI for both recommenders

[phkrief]

It would be great if we could use the same View for presenting the recommendation results.
Actually, the Code Recommendation view is pretty cool because:

• you retrieve the code which was selected for asking a recommendation
• you keep the history of the recommendations
  

So we could list both kind of recommendations in the same view and,

• if we select a code recommendation, see on the right subview the snipped code,
• if we select a Q&A recommendation, see on the right subview the links to the StackOverFlow posts

My 2 cents
