Bug 11939: set active currency when using English sample data

Bug 11939: set active currency when using English sample data

This patch offers a better default for currencies,
with USA dollar as default active currency.

To test the patch:
1)Install master without the patch, during web installation
select 'parameters.sql' file
2)Finish install and go to Administration -Currencies & Exchange rates
3)No active currency

4)Install master with this patch, during web installation
 select 'parameters.sql' file
5)Finish install and go to Administration -Currencies & Exchange rates
6)Now USA dollar is the active currency

NOTE: This does solve the problem of everything being NULL for active,
      and lacking an active value. It also corrects the description
      of the optional item to check related to currencies.
