Resolved an issue related to no proper valid/invalid event was

generated for the privilege control. Also, made changes in the
PrivilegeRoleModel, to allow to select a grantee only once for the
current user (as grantor), and omit them from other cell objects.

Valid/Invalid event was not properly triggered, whenever the child
attribute is a collection/model within a model (nested mode/collection
within model). This patch tried to take care of all such scenarios in
general.
