Bug 29092: Add timestamp to account-fines table column settings

Bug 29092: Add timestamp to account-fines table column settings

Table settings for the account_fines table (in the Patrons section, the
"Transactions" table in a patron account) are missing a checkbox for the
"Updated On" column. Because of this, one cannot hide the Updated On
column and any other values one sets here get applied to the wrong
columns.

This patch adds timestamp to account-fines column settings.
To test:

1) Navigate to columns settings page and modify account-fines tables
   column.
   => Note that if you hide e.g. account_type column, column
   credit_number is hidden on patrons account page
2) Apply patch and update database.
   => Account-fines column settings has now a option to hide timestamp.
   => Correct columns should now be hidden.
