placeholder object permission
init ci test
Separated object from model permission checks.
Since ModelBackend always returns False when object is given to has_perm
method, it is preventing model permssion to be acknowledged.
Added tests based on django-guardian as object-level-auth backend.
Since request.LANGUAGE_CODE might not always be avialable use cms.utils.get_language_from_request

get_language_for_request has a fallback mechanism for django-cms setups that don't need any i18n features.
