Revision Delete Rules

This module provides an action for rules to delete a node revision.

It is made with an attempt to cover the needs formulated in this issue https://drupal.org/node/1875468 of the node_revision_delete module.
I'm not sure if it should be a module on its own, or part of a bigger project (e.g. node_revision_delete and/or Revision Deletion

Other modules can act on the deletion of a revision by implementing hook_revision_delete_access_alter().

For example, integration with workflow_moderation could be added:

/**
 * Implementation of hook_revision_delete_access_alter().
 */
function workflow_moderation_revision_delete_access_alter(&$access, $node) {
  $access = _workbench_moderation_revision_access($node, 'delete');
}

I'd love to hear your thoughts about this piece of code, and possible integrations.
