list:list tag must be compartible with IteratorAggregate objects
----------------------------------------------------------------

                 Key: WACT-7
                 URL: http://jira.limb-project.com/browse/WACT-7
             Project: WACT
          Issue Type: New Feature
            Reporter: Denis Bazhenov


Now <list:list> tag do not use foreach statement for traverse around iterator. It use oldstyle rewind/next/valid etc calls. We cannot change this behaviour due some reasons. But we need have support for IteratorAggregate objects.

I offer inject additional check in generated code like:
$iterator = $this->getDatasource();
if ( $iterator instanceof IteratorAggregate ) {
  $iterator = $iterator->getIterator();
}
... generated code

This does not break current behaviour.
