* Changes to allow customer customfield to:

- get distinct customer per serial number from DB
- get cc:group value from DB for each customer
- get country_code from DB for customer
+ lookup and set CF for country
+ lookup and set CF for support region
+ set CC Group CF based on DB value for CC group
Added try/catch to catch exceptions when CC Group is misspelt.

Only allows a single CC Group value to be set and used.
