Removing unneeded context

This view was duplicated to the management section, and the
template pruned - the members' area no longer needs the
context here.
Adding a view for service information in the management area

This view is very similar to the members' view, but with
editing functionality. This change also removes editing
functionality from the members' view.

now they're restricted to users with kanisa.manage_services,
so we don't need the custom authorisation logic that just
checked is_authenticated.
