[3.7.X] Notification About Users' Subscriptions Expiring 1.00

Basically the title explains what this modification does. Works hand in hand with the subscription cron job so that when it compiles and sends out emails to the users it'll compile and sent out either an email or a private message to the user or email of your choice. Requires 3 file modifications to the subscriptions.php file in the includes/cron folder and all the settings and phrases are added by the import product option in the admincp.
