[ADD] account: import vendor bills files from dashboard

This adds a button to import several bills from the accounting dashboard: will create a new vendor bill for each, with the file attached to it. That file will be visible in the chatter (in enterprise) and allow easilly completion/encoding of it. This task also comes along with the import/export of xml files attached to the PDF files created from the invoice report.
