[IMP] payment_acquirer: improvements:

- added acquirer_reference standard field on the transaction, valid for most of acquirers
- fixed computation of partner_data before rendering the button, was broken when giving a
partner_id
- added support of tx_url to specify the form URL for the rendered button
- added support of submit_txt and submit_class to customize the submit button of the
rendered form
