Usability improvement for management of manual Gl transactions (OFBIZ-5559): thanks to Anahita Goljahani for the patch and to Pierre Smits for the tests and review.
Main changes introduced:
* new "Not available" data types that can be applied when transaction, account and resource type are not specified
* fixed some screens that were still displaying the account pk rather than the account code
* misc enhancements to the editing of manual transactions and chart of accounts
