We can set datastreams to inherit security directly without using auth quick template number.

The main focus is to remove configuration from public/misc/embargo_period_complete_check.php .

Wasn't able to test this directly using upstream!!!!  (possible issues with attachments).
But I did test running the embargo script on a downstream version of fez to release a file that had an embargo.

This approach wasn't what was originally discussed - originally we were thinking of having the id for an auth quick template that turned security inheritance on, and using this.  This approach bypasses the need to create this template and know its id and check it actually does the inherit.

If you prefer the other way let me know.... :)
