Changeset 885 for WAeUP_SRP/trunk/skins/waeup_student/clearance_edit_lib.pt

cleaned up several things:

1. the definitions for isManager, isStaff, and isClearanceOfficer

are now independant from eachother only based on roles or groups.
The Manager-Role is the superuser-role,
the is-Scripts document what is what.

since isStaff returns false if the member only has Manager-role,
in .cpsskins_theme it must now be:

if context.isStaff() or context.isManager():

return 'WAeUP_Backoffice'

todo: finish the merge of co_searchStudents and searchStudents
