Improve display of account_adjustment payments when viewing Full Details for a transaction.

[Michele Morgan]

When using the Prohibit negative balance org unit settings, each billing formerly voided is adjusted with a corresponding adjustment payment.

As a result, when staff users view full details of a transaction they may see a large number of adjustment payments making it difficult to see the actual payments made by the patron. It also can take much longer for the screen to load all the rows for display.

Improvements could include:

- Collapsing the adjustment payments to a single row for display purposes.
- Providing a way to filter out adjustment payments to make it clearer to staff what the patron has actually paid. (Currently adjustment payments are included in the Total Paid amount)

I'm also attaching a screenshot of the Full Details of a typical long-overdue-then-returned item where overdue fines have been adjusted. It's not uncommon for libraries to charge a $.05 per day fine with a maximum fine of $2.00. This results in 40 rows of billings and 40 rows of adjustment payments for the transaction.

I've attempted to address the concerns here as part of bug #1748986. It isn't an exact duplicate, so I will leave this separate for now, but I think if bug #1748986 goes in, we should consider this one satisfied as well.

Thanks Dan! The billing statement is a huge improvement and goes a very long way in addressing the issues raised here. I'm marking this bug as a duplicate of #1748986. I can think of a couple of tweaks to the main Bills screen in the web client, but will open a separate bug for that.
