-Fixed a bug so orders which are flagged as red i.e. not updated
still show as updated when you view the order they have had their status changed and the customer emailed,
when in reality it shouldn't have changed anything or sent emails
(thanks to Stubbsy for letting me know!)
-Cleaned up and commented the code
-Added a function to check if order exist and avoid "updating" status of inexistent orders
