Update Credit Check plugin to pull information from the Division and contact

Currently, the credit check plugin does not pull email address, address line 5 and cont no from the division/contact of the user using the plugin. This instead will use the information on these fields from the Model Ledger set in system settings. Address line 5, Email address and contact ID are pulled from the model ledger and not the division/contact. It would increase functionality if we could use the information off the division and contact information for these fields when we are creating the ledger for the user that is logged in. We could use the contact information from the contact that is logged in and the address line 5 of the company they are under.
