Nested pages variable

[SteenSchutt]

It'd be nice to have the pages variable but with nesting. That way I could create submenus without too much hassle.

{% for page in pages %}
<li><a href="{{ page.url }}">{{ page.title }}</a></li>
    <ul>{% for subpage in page.subpages %}
     <li><a href="{{ subpage.url }}">

If you catch my drift.
