verify 'Mapping API Calls to Privileges' wrt to move operations

fmeschbe, as discussed today, i suspect that the section about moving nodes (see http://jackrabbit.apache.org/oak/docs/security/privilege/mappingtoprivileges.html#Move_and_Import) doesn't not list the complete set of privileges required for a move operation, namely the ability to remove the source node itself (not just disconnect it from the parent).

i will verify that again and if true adjust the documentation (both for session and workspace move).
