title: Login member programmatically on Umbraco 7
body: <p>I am battling with this. In Umbraco 6 you could easily do this using:</p>
  
  <pre><code>Member.AddMemberToCache(
      Member.GetMemberFromEmail(email),
      true,
      new TimeSpan(0, 30, 0)
  );
  </code></pre>
  
  <p>I don't to find the same thing in the umbraco 7 member's service.</p>
