Bug 17076 - Format fines in patron search results table

Format the values in patron search results following syspref CurrencyFormat.

To verify:
- Search for patrons who have fines or credits
- In result table, column 'Fines' does not respect syspref CurrencyFormat
  (e.g. for FR)

To test:
- Apply patch
- Repeat steps above, verify that fines display as appropriate
- Change syspref Currencyformat, verify display
