IdStory Identity Manager

I've has to add new permission 'CHANGEPERMISSION' to identity - it works the same way as 'PASSWORDCHANGE' and is evaluated on identity roles page. Now is possible to show button for change identity permissions, only when logged identity has this permission and split 'UPDATE' and 'CHANGEPERMISSION' permission on identity - it's possible to create role request (changing identity's permission) for read only identities. RoleRequestByIdentityEvaluator behavior was updated - see doc. Tests are included.
