Add temporary access code to allow anon users to view products and their variations

This is the 2.x way, only the permissions are not defined at the moment.

Next week or so. We're busy on checkout at the moment.

I plan to work on theming the product page of my current project next week. I may post a patch here which includes the permissions.

@agoradesign
Permissions need to be done in the Entity API module, and then applied to every entity type. There's a pull request in the fago/entity repository already, but it hasn't been finished.

I've added a related issue, which fits to general topic of how to display the fields and attributes of variations within the product template

Here's a workaround for you. Implement this in a custom function, if you want to have general access to product entities. For a more fine grain, role-based approach, you'd need to define permissions of course:

function YOURMODULE_entity_access(\Drupal\Core\Entity\EntityInterface $entity, $operation, \Drupal\Core\Session\AccountInterface $account) {
  if ($operation == 'view' && $entity instanceof \Drupal\commerce_product\Entity\ProductInterface && $entity->isPublished()) {
    return \Drupal\Core\Access\AccessResult::allowed();
  }
  return \Drupal\Core\Access\AccessResult::neutral();
}

Retitling. Opened #2715273: Implement full permissions for every entity type to track the full fix.

Committed a combination of #11 and a variations fix.

Btw when removing my custom code, I saw that I obviously added the same variation part in the meantime :D

thanks anyway for the fix :)
