Several small usability improvements

- when manually encoding a payment line, get company currency as default currency
- Search on payment order numbers
- Direct search on bank journal name in payment orders
- remove widget="selection" on account.payement.mode : this object is rarely modified, so widget='selection' is not a time saver, but we miss the HTML link, which can be pretty convenient to check the configuration.
