Make sure the actions and conditions run fine, even with upgraded conditions, actions without settings for the new operations (view own, ..)

Added an upgrade for the removed workflow-ng action 'Set content permissions' - it'll be converted to an 'Grant content permissions by role' action

improved grant optimisations to don't write per node grants for roles, if authenticated users are granted access by content type permission

#325618: when per node permissions are disabled for a content type, fix removing possible created per-user ACLs.

Furthermore fixed using priority for ACLs.

improved mass updating content grants to make use of drupal's batch update, if the to be updated nodes exceed a certain limit,
improved mass updating content grants to only happen when really needed,
detect when content permissions are changed, which require updates to the node grants and fix the grants.

apply edit, edit own, delete and delete own access control settings by setting appropriate permissions

create branch 'DRUPAL-6--1'.
