Bug 17078 - Format fines on opac-account.pl

Bug 17078 - Format fines on opac-account.pl

To verify:
- Log in to OPAC as a user who has fines or credits
- Go to page "your fines"
- Verify that values for "Fine amount", "Amount outstanding"
  and "Total due" are not formatted as defined in syspref CurrencyFormat
  (e.g. for FR)

To test:
- Apply patch
- Repeat steps above
- Verify that values are formatted as appropriate with different
  settings for syspref CurrencyFormat

Note: This patch does not force text alignment to the right.
      Text alignement can be done using syspref OPACUserCSS
      (td.sum, td.credit, td.debit)
