*DS* Anti (copy & transfer)

This funktion allows you to give away scripts with copy & transfer permissions and force the reseller to change the permission. Additionally the script will delete itself when the customer of the reseller receives it with both permissions. Because it is a global function, it can be used universally.

Make sure that you not give away scripts with modify rights which contains this function.
