title: Git Extensions Does Not Recognize Github RSA Signature
body: <p>When trying to clone a repository through the newest version of Git Extensions a window appears which states:</p>
  
  <blockquote>
    <p>The server's host key is not cached in the registry. You
    have no guarantee that the server is the computer you
    think it is.</p>
  </blockquote>
  
  <p>Normally when using the command version of SSH you can add this footprint to the list of approved hosts, but using the front-end it doesn't work as expected.</p>
