Only users with the manage workspace permission can remove members
add test to prove that only workspace admins can remove members
Regular users can only search for and add new users. They cannot remove users. Admins should be able to add and remove users.
Simplify the template logic (slightly)
simplify can_add_users.
if the workspace is admin managed, hide the form elements from regular users
this line is no longer needed
Add a test for can_add_users.
This is not necessarily the edit roster page any more
Add author links to roster
Roster port let requires the view roster permission
update test with new roster title
