ui: BeFront helper metaAll and metaDc not correct for sections

[stefanorosanelli]

$beFront->metaAll() and $beFront->metaDc()
don't give section metadata but first contents metadata when you are on a section
[[BR]]

example: http://docs.bedita.com/core -- meta "description", "DC:description",....and all other metadata relate to first document in section not to section
[[BR]]

look at metadata for first document: there are no differences

0713b2e Fix in get_description. If contentRequested then get first object in section metadata, section otherwise.
To test publication root metadata, override pagesController method homePage().
I used the sample frontend bookish, with following method:

public function homePage() {
    $filter = array("object_type_id" => Configure::read("objectTypes.section.id"));
    $child = $this->BeTree->getChildren($this->publication["id"], $this->getStatus(), $filter, null, true, 1, 1);
    $this->action = 'section';
    $this->section($this->publication["id"]);
}
