title: How to customize Bootbox.js prompt options
body: <p>I am trying to customize bootboxjs.prompt options, but it seems that it doesn't allow an options object as a parameter</p>
  
  <p>This is the example from <a href="http://bootboxjs.com/index.html#api">http://bootboxjs.com/index.html#api</a></p>
  
  <pre><code>bootbox.prompt("What is your name?", function(result) {                
    if (result === null) {                                             
      Example.show("Prompt dismissed");                              
    } else {
      Example.show("Hi &lt;b&gt;"+result+"&lt;/b&gt;");                          
    }
  });
  </code></pre>
  
  <p>This is what I am trying to pass:</p>
  
  <pre><code>var promptOptions = {
    title: "Custom label",
    buttons: {
      confirm: {
        label: "Save"
      }
    }
  };
  
  bootbox.prompt(promptOptions, function(result) {                
    if (result === null) {                                             
      console.log("Prompt dismissed");                              
    } else {
      console.log("Hi "+result);                          
    }
  });
  </code></pre>
  
  <p>How can I customize the title and buttons label ?</p>
