Merge lp:~openerp-dev/openobject-server/6.0-opw-17993-vro into lp:openobject-server/6.0

Hello,

If the "Rounding factor" (rounding) of a currency is set to 0.0, it will nullify the value of rounded amounts.

To regenerate the issue (Case#17993):
1. Create a new currency with rounding left as 0.0
2. Use this currency in an invoice
3. Add invoice lines and observe that the Sub-total field has value 0.0 because of rounding of the currency.

This fixes the issue.

This fix also sets the rounding default to 0.01

Thanks
