title: Set the subject mail app - people app
body: <p>I would like to share some content from my Windows 8 Metro App to the Mailto App.
  I've implemented the People App, the user can select some people and when clicked on a button the selected people are displayd (name + image) and the charm bar (share) opens up. I allready set some content (body) to sent in the email. </p>
  
  <p>Now what I'm looking for, can I set the subject from the mail programmatically (people choosen from the people app)?</p>
