labels are not translated automatically

[meltzow]

If I added a new Page, the label is not translated. Other translations are working fine. For example

'wallpapers' => array( 'name' => 'wallpapers', 'options' => array( 'label' => 'menu_wallpapers', 'route' => 'zfcadmin/wallpaper', 'params' => array( 'action' => 'index' ) ) ),

I haven't done anything with translation yet. Feel free to submit a PR.
