title: JIRA JQL: Issues resolved in the current sprint
body: <p>I would like to be able to filter for issues that are have been resolved in the current sprint. Generally this would be used to prevent issues resolved in a previous sprint but delayed in testing (not reopened) showing up when we are discussing what developers achieved this sprint.</p>
  
  <p>Closed issues should also appear, but they are not a problem, as if they were closed last sprint, they wouldn't roll over into this one anyway.</p>
  
  <p>In mock-JQL, it would go something like this:</p>
  
  <pre><code>project = "Project name" AND status in (resolved, closed) AND statusChanged() &gt; startOfWeek() 
  </code></pre>
  
  <p>I have seen <code>startofweek()</code> and friends, but not something like <code>startofsprint()</code>. </p>
  
  <p>We have JIRA OnDemand, so we can't install local Java add-ons.</p>
  
  <p>Any way to get this information?</p>
