[BUGFIX] Disable restricted users to handle page records in pagetree

This patch hides the context menu entries 'disable'/'enable', 'edit',
'new', 'cut', 'copy', 'paste into', 'paste after' and 'delete' in
case an user is restricted to only non default languages.
Additionally it throws an error message if the user is trying to edit
a page title directly in the pagetree via double click.
