Support middle click navigation

When the user does a middle click on a link which originally opens a
new tab (target="_blank"), the newly created RenderView is hidden, so
the new tab has no visible content. We need to unhide it explicitly.

This also adds background tab support for the Quick example browsers
and fixes the profile mismatching warning in the case when we adopt
a new tab without WebContents.
