title: Typo3: External URL should open with target=_blank
body: <p>I have created a page with the type <code>external URL</code>. In the tab "General" I can specify the protocol and the URL. In another tab I can specify the URL alias and the target. But the target is already _blank. In the frontend the link still opens in the same window. I'm using Typo 4.5.</p>
