0011522: improve handling of group-lists

Admin / Addressbook: fix group - list concept

* Addressbook_Controller_List
** adding or removing list members now checks manage
   accounts right if list is a grouplist
** changing list properties now checks manage accounts
   right if list is a grouplist and property is a group
   property too.
** for grouplists above changes are send to the group
   controller too, to change associated group too.
** _inspectBeforeCreate allows creation of lists of type
   group, checks for rights & proper group_id

* Addressbook_Controller_Contact
** _inspectBeforeUpdate checks if account data will be
   changed, if so, rights are checked
