Requires database changes, you need to log all terminals out.

Apologies for disruptions this morning.  This version hopefully will straighten everything out.

Fixes:

• Total account balance displayed is wrong.  Individual debtor/depositor balances are okay. Should now be fixed.
• System would crash at multiple points in c9.  For example when adding a new customer when you key in phone numbers as part of add. Would crash searching for customers with same phone number. Now also fixed
• For dealers that have not updated past 4.579, also includes changes to actual database upgrade to make it more reliable.  Prior updates could cause c9 to fail to upgrade due to issues with conflicts between supplier and customer codes.  Also fixed
